How to store a stool sample

  • collect your poo (stool) sample in a completely clean (sterile) container
  • store the container in a fridge in a sealed plastic bag if you can’t hand it in straight away

Collecting a stool sample

Your GP or another healthcare professional, such as a nurse, should explain how to collect the sample. It should be collected in a clean, dry screw-top container.

Your doctor or a member of staff at the hospital will give you a plastic (specimen) container to use, although you can use any clean container as long as you can seal it.

Try not to collect pee (urine) or water from the toilet along with the poo, but don’t worry if you do. If you need to pee, do this first before collecting the poo.

To collect the sample:

  • label a clean, screw-top container with your name, date of birth and the date
  • place something in the toilet to catch the poo, such as a potty or an empty plastic food container, or spread clean newspaper or plastic wrap over the rim of the toilet
  • make sure the poo doesn’t touch the inside of the toilet
  • use the spoon or spatula that comes with the container to collect the poo, then screw the lid shut
  • if you’ve been given a container, aim to fill around a third of it – that’s about the size of a walnut if you’re using your own container
  • put anything you used to collect the poo in a plastic bag, tie it up and put it the bin
  • wash your hands thoroughly with soap and warm running water

Follow any other instructions your doctor has given you.

Storing a stool sample

Your sample of poo must be fresh – if it is not, the bacteria in it can multiply. This means the levels of bacteria in the stool sample won’t be the same as the levels of bacteria in your digestive system. If the levels of bacteria don’t match, the test results may not be accurate.

Your sample should be handed in as soon as possible, as sometimes it can’t be analysed after being refrigerated – your doctor will tell you if this is the case.

If you can’t hand your sample in immediately, find out how long it can be kept in the fridge. Your GP or the healthcare professional who requested the test will be able to tell you. If you can store it in the fridge, put the container in a sealed plastic bag first.

What are stool samples used for?

Your GP or another healthcare professional may ask you for a stool sample to help them diagnose or rule out a particular health condition.

Poo contains bacteria and other substances that are in the digestive system.

By testing the levels of these substances and bacteria in your poo, it’s possible to work out what’s happening in your digestive system.

For example, the sample can be tested to help diagnose:

  • gastroenteritis – a common condition that causes diarrhoea and vomiting, and is usually the result of a bacterial or viral tummy bug
  • inflammatory bowel disease – such as Crohn’s disease, a condition that causes inflammation of the lining of the digestive system, and ulcerative colitis, a condition where the colon and rectum become inflamed

How to store a stool sample

You may be wondering, What Are Intestinal Parasites? (Click Here) Intestinal parasites are organisms that infect people or animals, living in the intestines and robbing the host of nutrients. One of the best protections against these parasites is a screening a stool sample for parasite eggs. Here are our tips for collecting your pet’s stool sample!

1. The Fresher the Better

If your cat’s or dog’s poop has been sitting around for more than one day, please trash it. A cat’s or dogs’s feces that is older than 1 day will not give the appropriate diagnostic information, because the eggs have hatched and are no longer present.

2. Storage is Vital

Should you have an appointment the day of the stool sample collection, please store in the refrigerator. Please do not allow the sample to bake in the hot sun, in your car, or freeze in the freezer.

3. Smaller is Better.

The appropriate size to collect can be the size of a walnut, about 2 sugar cubes, or even the size of the tablespoon.

4. Use a Fecal Sample Collector or Choose Your Container Sensibly

We recommend pre-paying for your fecal sample to obtain a fecal sample collector to take home. Other useful containers can be an old pill bottle, plastic container, etc. Be cautious about choosing anything that could be confused for a usable food container.

Poop bags should be tied or even knotted. No paper towel or grocery bags, please.

5. Pure Poop is Best

Cat litter containing urine is not going to reveal parasites. A stick covered with poop will be rejected. Stool with leaves will not be an appropriate sample.

Stool (or feces) is usually thought of as nothing but waste — something to quickly flush away. But bowel movements can provide doctors with valuable information as to what’s wrong when a child has a problem in the stomach, intestines, or another part of the gastrointestinal system.

A doctor may order a stool collection to test for a variety of possible conditions, including:

  • allergy or inflammation in the body, such as part of the evaluation of milk protein allergy in infants
  • infection, as caused by some types of bacteria, viruses, or parasites that invade the gastrointestinal system
  • digestive problems, such as the malabsorption of certain sugars, fats, or nutrients
  • bleeding inside of the gastrointestinal tract

The most common reason to test stool is to determine whether a type of bacteria or parasite may be infecting the intestines. Many microscopic organisms living in the intestines are necessary for normal digestion. If the intestines become infected with harmful bacteria or parasites, though, it can cause problems like certain types of bloody diarrhea, and testing stool can help find the cause.

Stool samples are also sometimes analyzed for what they contain; for instance, examining the fat content. Normally, fat is completely absorbed from the intestine, and the stool contains virtually no fat. In certain types of digestive disorders, however, fat is incompletely absorbed and remains in the stool.

Collecting a Stool Specimen

Unlike most other lab tests, stool is sometimes collected by the child’s family at home, not by a health care professional. Here are some tips for collecting a stool specimen:

  • Collecting stool can be messy, so be sure to wear latex gloves and wash your hands and your child’s hands well afterward.
  • Many kids with diarrhea, especially young children, can’t always let a parent know in advance when a bowel movement is coming. Sometimes a hat-shaped plastic lid is used to collect the stool specimen. This catching device can be quickly placed over the toilet bowl or your child’s rear end to collect the specimen. Using a catching device can prevent contamination of the stool by water and dirt. If urine contaminates the stool sample, it will be necessary to take another sample. Also, if you’re unable to catch the stool sample before it touches the inside of the toilet, the sample will need to be repeated. Fishing a bowel movement out of the toilet does not provide a clean specimen for the laboratory to analyze.
  • Another way to collect a stool sample is to loosely place plastic wrap across the rim of the toilet, under the seat. Then place the stool sample in a clean, sealable container before taking to the laboratory. Plastic wrap can also be used to line the diaper of an infant or toddler who is not yet using the toilet.

The stool should be collected into clean, dry plastic jars with screw-cap lids. You can get these from your doctor or through hospital laboratories or pharmacies, although any clean, sealable container could do the job. For best results, the stool should then be brought to the laboratory immediately.

If the stool specimen is going to be examined for an infection, and it’s impossible to get the sample to the laboratory right away, the stool should be refrigerated, then taken to the laboratory to be cultured as soon as possible after collection. When the sample arrives at the lab, it is either examined and cultured immediately or placed in a special liquid medium that attempts to preserve potential bacteria or parasites.

The doctor or the hospital laboratory will usually provide written instructions on how to successfully collect a stool sample; if written instructions are not provided, take notes on how to collect the sample and what to do once you’ve collected it.

If you have any questions about how to collect the specimen, be sure to ask. The doctor or the lab will also let you know if a fresh stool sample is needed for a particular test, and if it will need to be brought to the laboratory right away.

Most of the time, disease-causing bacteria or parasites can be identified from a single stool specimen. Sometimes, however, up to three samples from different bowel movements must be taken. The doctor will let you know if this is the case.

Testing the Stool Sample

In general, the results of stool tests are usually reported back within 3 to 4 days, although it often takes longer for parasite testing to be completed.

Examining the Stool for Blood

Your doctor will sometimes check the stool for blood, which can be caused by certain kinds of infectious diarrhea, bleeding within the gastrointestinal tract, and other conditions. However, most of the time, blood streaking in the stool of an infant or toddler is from a slight rectal tear, called a fissure, which is caused by straining against a hard stool (this is fairly common in infants and kids with ongoing constipation).

Testing for blood in the stool is often performed with a quick test in the office that can provide the results immediately. First, stool is smeared on a card, then a few drops of a developing solution are placed on the card. An instant color change shows that blood is present in the stool. Sometimes, stool is sent to a laboratory to test for blood, and the result will be reported within hours.

Culturing the Stool

Stool can be cultured for disease-causing bacteria. A stool sample is placed in an incubator for at least 48 to 72 hours and any disease-causing bacteria are identified and isolated. Remember that not all bacteria in the stool cause problems; in fact, about half of stool is bacteria, most of which live there normally and are necessary for digestion. In a stool culture, lab technicians are most concerned with identifying bacteria that cause disease.

For a stool culture, the lab will need a fresh or refrigerated sample of stool. The best samples are of loose, fresh stool; well-formed stool is rarely positive for disease-causing bacteria. Sometimes, more than one stool will be collected for a culture.

Swabs from a child’s rectum also can be tested for viruses. Although this is not done routinely, it can sometimes give clues about certain illnesses, especially in newborns or very ill children. Viral cultures can take a week or longer to grow, depending on the virus.

Testing the Stool for Ova and Parasites

Stool may be tested for the presence of parasites and ova (the egg stage of a parasite) if a child has prolonged diarrhea or other intestinal symptoms. Sometimes, the doctor will collect two or more samples of stool to successfully identify parasites. If parasites — or their eggs — are seen when a smear of stool is examined under the microscope, the child will be treated for a parasitic infestation. The doctor may give you special collection containers that contain chemical preservatives for parasites.

So – we have been having a running discussion with people in my lab about one key issue in microbiome studies – how does one store samples prior to doing DNA extractions and does it matter? As background for those who do not do this kind of work – the general principle behind DNA based analysis of microbes and microbial communities is that you can go to a sample (soil, water, air, tissue, etc) and extract DNA from that sample and then study the microbes in the sample by looking at the DNA.

This can be represented in the following cartoon:

How to store a stool sample

But one of the challenges is, it is not always possible or ideal to directly isolate DNA from ones sample. And how samples are processed can affect what DNA comes out the other end and thus can affect results.

From a simple examination of a set of projects, it seems to me there are something like five main classes of approaches used in going from sample to DNA which I represent in this cartoon. Some details are in the text below.

How to store a stool sample

  1. Freeze. Collect samples, whatever they may be (soil, swabs, tissue, etc) and freeze them, preferably at a very cold temperature. Then, when it is time to do DNA extractions, thaw them out and extract DNA.
  2. Buffer. Mix with some buffer or DNA stabilization / extraction solution and then let sit, possibly at room temperature, for an extended period of time. Then extract DNA.
  3. Process. Process fresh samples immediately (or as rapidly as possible) and extract DNA and then store the DNA for later use.
  4. Dry. Collect samples and dry them and then store them dried. This is done usually in cases where the main goals do not involve DNA analysis. But sometimes people would like to go to the samples afterwards and try to study microbes in and on the samples.
  5. Fix. Collect samples and then mix them with some sort of fixative (e.g., formalin, alcohol). This is done with all sorts of samples where the main goal is to do something other than DNA analysis. But then, after the fact, many people would like to get DNA out of these samples.

Of course, this is a bit of an oversimplification, but to me these seem to be the main categories of what is commonly done with samples. There are also other “minor” categories of what is done with samples but these five seem to cover most cases.

I am writing this post for three main reasons.

First, I would like to generate a community discussion around what people do with their samples and why. For example, I was told recently that there is some literature indicating the freezing fecal samples directly (rather than putting in some buffer) is less than ideal because the microbiomes retrieved from such samples change over time.

Second, I would like this to serve in a way as a place for people to ask questions about recommendations for what to do for their samples. For example, I got asked yesterday about how to collect plant leaf samples in the field for microbiome studies if one does not have access to a freezer.

Third, I would like to use this as a launching pad for starting to collect together formal protocols that people use in microbiome and microbiology of the built environment studies. We may use Protocols for this, but am still experimenting on systems.

So please -anyone who works on microbiome studies – we would welcome comments about methods and best practices and references and any other detail you can provide.

Although great interest has been displayed by researchers in the contribution of gut microbiota to human health, there is still no standard protocol with consensus to guarantee the sample quality of metagenomic analysis. Here we reviewed existing methodology studies and present suggestions for optimizing research pipeline from fecal sample collection to DNA extraction. First, we discuss strategies of clinical metadata collection as common confounders for microbiome research. Second, we propose general principles for freshly collected fecal sample and its storage and share a DIY stool collection kit protocol based on the manual procedure of Human Microbiome Project (HMP). Third, we provide a useful information of collection kit with DNA stabilization buffers and compare their pros and cons for multi-omic study. Fourth, we offer technical strategies as well as information of novel tools for sample aliquoting before long-term storage. Fifth, we discuss the substantial impact of different DNA extraction protocols on technical variations of metagenomic analysis. And lastly, we point out the limitation of current methods and the unmet needs for better quality control of metagenomic analysis. We hope the information provided here will help investigators in this exciting field to advance their studies while avoiding experimental artifacts.

What is a chymotrypsin in stool test?

This test measures the amount of chymotrypsin in a stool sample. Chymotrypsin is an enzyme released by the pancreas during digestion. If lower than normal amounts are released, it may mean your pancreas isn’t making enough enzymes to digest your food properly. This is known as pancreatic insufficiency.

Pancreatic insufficiency is most often caused by chronic pancreatitis, a swelling of the pancreas. It may also be caused by cystic fibrosis (CF), a genetic disorder that causes mucus to build up in the lungs and other organs, including the pancreas. People with CF often have trouble absorbing nutrients from food.

Your sample may also be tested for trypsin, an enzyme released by the pancreas along with chymotrypsin.

Other names: fecal chymotrypsin, trypsin and chymotrypsin stool test

What is it used for?

A chymotrypsin in stool test is used to help diagnose conditions that affect the pancreas, such as:

  • Pancreatitis
  • Cystic fibrosis
  • Malnutrition, a condition in which your body does not get the calories, vitamins, and/or minerals needed for good health

Why do I need a chymotrypsin in stool test?

You may need this test if you have symptoms of a pancreatic disorder. These include:

  • Chronic diarrhea
  • Abdominal pain
  • Foul-smelling, greasy stools
  • Weight loss
  • Frequent sinus infections

What happens during a chymotrypsin in stool test?

You will need to provide a stool sample. Your health care provider will give you specific instructions on how to collect and send in your sample. Your instructions may include the following:

  • Put on a pair of rubber or latex gloves.
  • Collect and store the stool in a special container given to you by your health care provider or a lab. You may get a device or applicator to help you collect the sample.
  • Make sure no urine, toilet water, or toilet paper mixes in with the sample.
  • Seal and label the container.
  • Remove the gloves, and wash your hands.
  • Return the container to your health care provider or the lab by mail or in person.

Will I need to do anything to prepare for this test?

You don’t need any special preparations for a chymotrypsin in stool test.

Are there any risks to this test?

There is no known risk to having a stool test.

What do the results mean?

Your results will show whether the amount of chymotrypsin in your stool is normal or below normal. Your results may also include the amount of trypsin found.

If the amount of chymotrypsin and/or trypsin is below normal, it may mean your pancreas isn’t making enough enzymes to digest your food properly. But the test can’t diagnose any specific disorders by itself. Your health care provider will need to order more tests. These may include the following, which measure different pancreatic enzymes:

If you have questions about your results, talk to your health care provider.

Recommendations for long-term care facilities

Clostridioides (Clostridium) difficile infection (CDI) may be suspected in residents with new onset of diarrhea who have 3 or more unformed stools (conform to the shape of the container) in a 24-hour period. To determine if a patient has CDI, consider both clinical symptoms and lab test results.

Facilities can use multiple tests to confirm or to assist in confirming CDI in symptomatic patients. However, it is important to know what test is being used because they have widely varying turn-around times, sensitivities, specificities, positive predictive values, and negative predictive values.

Lab tests

  • Culture
    • Most sensitive test available, but often associated with false-positive results due to presence of non-toxigenic strains
    • Labor intensive and requires careful laboratory quality control
    • Results are available within 48-96 hours
  • Antigen Detection
    • Detects the presence of C. difficile antigen (GDH) by latex agglutination or immunochromatographicassays
    • Rapid test results ( 3 negative specimens processed.

      “Three negative specimens from this patient have already been processed in the last week. Test cancelled.”

      Positive within 7 days

      “Please refer to previous positive C. difficile toxin result.”

      Submitted in enteric pathogen transport medium or SAF container.

      “Specimen received in enteric pathogen transport medium. Unsuitable for C. difficile testing. Please repeat.”
      -OR-
      “Specimen received in SAF (fixative for parasite). Unsuitable for C. difficile toxin testing. If you have any questions, please call the Microbiology Lab.”

      Colon examination

      In some cases, examination of the colon can be used to help confirm a diagnosis of CDI. If C. difficile colitis is not accompanied by pseudomembrane formation, endoscopic findings are relatively nonspecific, but a biopsy specimen may reveal changes typical of pseudomembranous colitis.

      Endoscopy

      • Pseudomembranous colitis can only be diagnosed by direct visualization of pseudomembranes on lower gastrointestinal endoscopy
      • At least 90% of patients with pseudomembranous colitis demonstrate either C. difficile or its toxin in stool samples
      • Because of its cost, risk to the patient, and the availability of other diagnostic tests, endoscopy is usually reserved for special situations
      • The American College of Gastroenterology Guidelines recommend endoscopy for situations such as the following:
        • a rapid diagnosis is needed and test results are delayed or insensitive tests are used
        • the patient has an ileus and stool is not available
        • other colonic diseases that can be diagnosed with endoscopy are being considered

      Imaging tests

      • Computerized tomography (CT) scan
        • Provides detailed images of the colon
        • This scan can show a thickening of the wall of the colon, which is common in pseudomembranous colitis

      • Are There Other Stool Tests for Colorectal Cancer?

      The fecal occult blood test (FOBT) looks for the presence of microscopic blood in the feces, which may be a sign of a problem in your digestive system.

      What Causes Blood to Appear in Stool?

      Blood may appear in the stool because of one or more of the following conditions:

      • Benign (non-cancerous) or malignant (cancerous) growths or polyps of the colon
      • Hemorrhoids (swollen blood vessels near the anus and lower rectum that can rupture, causing bleeding)
      • Anal fissures (splits or cracks in the lining of the anal opening)
      • Intestinal infections that cause inflammation
      • Ulcers
      • Ulcerative colitis
      • Crohn’s disease
      • Diverticular disease, caused by outpouchings of the colon wall
      • Abnormalities of the blood vessels in the large intestine

      Gastrointestinal bleeding may be microscopic (invisible to the eye) or may be easily seen as red blood or black tar-like bowel movements, called melena.

      How Do I Take a Fecal Occult Blood Test?

      The fecal occult blood test requires the collection of 3 small stool samples. Usually the samples are a bit of stool collected on the end of an applicator. The stool samples should be taken one day apart, because colon cancers may bleed from time to time, rather than consistently.

      You can purchase fecal occult blood test kits at the pharmacy to perform the test at home, or your doctor may give you the home test during one of your appointments. These tests provide specific instructions, and most offer a toll-free number to call if you have questions.

      The stool samples are collected in a clean container and evaluated by detecting color changes on a test card, or by sending the samples, in a special container and envelope, directly to the doctor’s office for analysis. Your doctor may examine the samples with a microscope or with chemical tests.

      How Should I Prepare for the Fecal Occult Blood Test?

      The fecal occult blood test results are largely affected by how you prepare for the test, so it is important to follow the instructions carefully.

      Because certain foods can alter the test results, a special diet is often recommended for 48-72 hours before the test. The following foods should be avoided during that time:

      • No raw fruits
      • No raw vegetables
      • No red meat; you can eat chicken and porkВ
      • Less than 250 mg per day of vitamin C-enriched foods or beverages in the 72 hours leading up to the test

      Your doctor will go over your medicines with you before the test, because you may need to stop taking certain medicines 72 hours before the test.

      How Often Do I Need to Do the Fecal Occult Blood Test?

      A colonoscopy is the preferred screening method for colorectal cancer. If you are not having this test done as needed, then you should get a fecal occult blood test every year, beginning at age 45. This test may be done along with a flexible sigmoidoscopy every five years to check for colorectal polyps or cancer.

      What Do the Fecal Occult Blood Test Results Mean?

      Because small amounts of blood normally appear in the stool, tests for occult blood are designed to detect larger quantities of blood.

      A positive fecal occult blood test means that blood has been found in the stool. Your doctor will have to determine the source of the bleeding, either by doing a colonoscopy or by doing an examination to determine if the bleeding is coming from the stomach or small intestine.

      A negative test result means that no blood was found in the stool sample during the testing period. You should continue to follow your doctor’s recommendations for regular screening.

      Are There Other Stool Tests for Colorectal Cancer?

      The fecal immunochemical test (FIT) is the test of choice over the fecal occult blood test. This testВ can be done at home.В For this test, you take a sample from your stool with a brush and dab it onto a special card. This test may be easier to do at home than the FOBT. There are no drug or food restrictions.

      В The stool DNA test or FIT-DNA test is another option for the early detection of CRC. This test spots cellular changes that could mean you have cancer or pre-cancerous polyps. It also can detect blood in the stool. You use a kit at home to collect a stool sample and send it to a lab for analysis. This test is still being studied to see how well it works to findВ colorectal cancer.

      How to store a stool sample

      This page was fact checked by our expert Medical Review Board for accuracy and objectivity. Read more about our editorial policy and review process.

      At a Glance

      Why Get Tested?

      To detect and measure excess fat in the stool; to help diagnose conditions causing malabsorption, which is difficulty digesting food and absorbing nutrients

      When To Get Tested?

      When you have symptoms of malabsorption, such as persistent diarrhea and fatty stools

      Sample Required?

      A random stool collection; sometimes a 72-hour stool collection

      Test Preparation Needed?

      For a 72-hour stool collection, follow the instructions from the lab performing the test or your health practitioner. This may include consuming 50-150 grams of fat a day in your diet for 2-3 days prior to and during the stool collection period.

      What is being tested?

      This test measures the amount of fat in a stool sample. Excess fecal fat (termed steatorrhea) may be an indication that your digestive system is not working properly and/or that you have a condition affecting the digestion of food and absorption of nutrients, also called malabsorption.

      The body digests foods in stages: proteins, fats, and carbohydrates are broken down, in the stomach by acid and enzymes and in the small intestines by enzymes produced by the pancreas and bile from the liver, into their component parts. They are then absorbed, primarily in the small intestines. Finally, the nutrients are transported throughout the body and used or stored.

      • If there are not enough pancreatic enzymes or bile available, then fat and other foods cannot be properly digested and cannot be efficiently absorbed. If a condition prevents the intestines from absorbing nutrients, then they are eliminated in the stool. In both cases – improper digestion or absorption – you can experience symptoms associated with malabsorption and, in severe cases, symptoms of malnutrition and vitamin deficiency. If the condition prevents you from digesting and absorbing fats from the diet, then excess fat is present in the stool and you may experience persistent diarrhea with stools that are loose and foul-smelling (steatorrhea).

      Fat in stool may be detected with the qualitative fecal fat test, which generally determines the presence or absence of excess fat. This test is performed by placing a suspension of treated or untreated stool onto a glass slide, adding a fat stain, and observing the number and size of fat globules that are present. It should be performed by an experienced professional.

      Quantitative measurements of fecal fat, though somewhat more accurate, are less commonly performed. However, they are considered the gold standard. They require a timed stool collection and a dietary sheet to help calculate the total fat intake during the collection period, usually a 72-hour stool collection. Results are reported as the amount of fat eliminated in stool per day (24 hours).

      Another quantitative test is called the acid steatocrit, which provides a rapid but less exact measure of the amount of fat in the stool. It is a less complicated test that can be used on a random stool sample.

      How is the sample collected for testing?

      For a 72-hour stool collection, save all stool during the collection time period in the container(s) provided. It may be collected in a variety of ways, such as on plastic wrap, but should not be contaminated by urine, toilet water, or toilet paper. For a random sample, collect a single specimen in the same fashion.

      Is any test preparation needed to ensure the quality of the sample?

      For a 72-hour stool collection, follow your healthcare provider’s instructions and dietary recommendations. This may include consuming a fat-controlled diet containing 50-150 grams of fat a day for 2-3 days prior to and during the stool collection period. You will also be asked to avoid certain oils and fat substitutes during the collection as these can invalidate the test result. You may also be asked to discontinue using exogenous pancreatic supplements if you are using any.

      Guaiac fecal occult blood test

      This test can detect small amounts of blood in stool. It requires abstaining from red meat and certain medications for a number of days before. An FOBT is more specific to finding blood from further up the digestive tract, such as the stomach.

      • Looks for blood in stool
      • Doctor may ask you to avoid certain foods and medicines
      • No risk involved
      • Inexpensive and generally covered by insurance

      Advantages

      • Inexpensive; covered by most insurance
      • Can be simple to complete
      • Can be completed in the comfort of your own home

      Disadvantages

      • Cannot identify polyps; can only detect signs of cancer
      • Will need a colonoscopy if test is positive
      • Patients may find test unpleasant
      • Requires strict adherence to the test protocol for the test to be accurate (restricted diet and multiple days of stool collection)
      • High false positive rate — non-cancerous conditions may also cause blood in the stool and not specific for human blood
      • May miss tumors that bleed in small amounts or not at all

      What can I expect for a bill?

      Average cost before insurance: about $5

      Will my insurance cover it?

      Medicare covers FOBT once a year for individuals 45 and over. Most other insurances cover the test too; talk to your carrier.

      The facts

      The guaiac fecal occult blood test (FOBT) is used to find occult blood (or blood that can’t be seen with the naked eye) in stool. The idea behind this test is that blood vessels at the surface of larger polyps or cancers are often fragile and easily damaged by passing stool. The damaged blood vessels usually release a small amount of blood into the stool, but only rarely is there enough bleeding to be visible in the stool. The FOBT is an easy way to determine whether there is blood in your stool, which could be the result of polyps or colorectal cancer.

      So how does it work? The FOBT detects blood in the stool through a chemical reaction. However, it can’t tell if the blood is from the colon, rectum, or from other parts of the digestive tract, like the stomach. If this test is positive, a colonoscopy will be needed to find the reason for the presence of blood. Although cancers and polyps can cause blood in the stool, there are other causes too. Ulcers, hemorrhoids, diverticulosis (tiny pouches that form at weak spots in the colon wall) or inflammatory bowel disease (colitis) may also cause blood in your stool.

      This screening test is done with a kit that you can use in the privacy of your own home. Another important part of this kit and test is that it requires you to check more than one stool sample. Also, unlike some other screening tests (including colonoscopy), this one must be repeated every year.

      The prep

      Some foods or drugs can affect the outcome of the FOBT, so your doctor may suggest that you avoid the following before this test:

      • Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil), naproxen (Aleve) or aspirin (more than one adult aspirin per day), for seven days before testing
      • Vitamin C in excess of 250 mg daily from either supplements or citrus fruits and juices for three days before testing
      • Red meats for three days before testing, as the components of blood in the meat may cause the test to show positive

      The procedure

      Begin with all of your supplies ready and in one place. Supplies will include a test kit, test cards, either a brush or wooden applicator and a mailing envelope. The kit will give you detailed instructions on how to collect the stool. The instructions below can be used as a guide, but your kit instructions could be a little different, so always follow those instructions first.

      First, you’ll need to collect a sample from your bowel movement. You can place a sheet of plastic wrap or paper loosely across the toilet bowl to catch the stool or you can use a dry container to collect the stool – whichever you prefer. Make sure the stool specimen does not mix with urine. After you obtain a sample, flush the remaining stool down the toilet.

      Use a wooden applicator or a brush to smear a thin film of the stool sample onto one of the slots in the test card or slide.

      Next, collect a specimen from a different area of the same stool and smear a thin film of the sample onto the other slot in the test card or slide.

      Close the slots and put your name and the date on the test kit. Store the kit overnight in a paper envelope so it can dry.

      Repeat the test on your next two bowel movements, if instructed. Most tests require collecting more than one sample from different bowel movements to improve the accuracy of the test. Because many cancers don’t bleed all of the time, blood may not be present in all stool samples.

      Place the test kit in the mailing pouch provided and return it to your doctor or lab as soon as possible (but within 14 days of taking the first sample).

      The big ‘what if…’

      For the FOBT, a positive test result indicates that abnormal bleeding is occurring somewhere in the digestive tract. As we’ve stated, this blood loss could be due to a number of things besides cancer, so if the test finds blood, a colonoscopy will be needed to look for the source.

      Abstract

      As the number of human microbiome studies expand, it is increasingly important to identify cost-effective, practical preservatives that allow for room temperature sample storage. Here, we reanalyzed 16S rRNA gene amplicon sequencing data from a large sample storage study published in 2016 and performed shotgun metagenomic sequencing on remnant DNA from this experiment. Both results support the initial findings that 95% ethanol, a nontoxic, cost-effective preservative, is effective at preserving samples at room temperature for weeks. We expanded on this analysis by collecting a new set of fecal, saliva, and skin samples to determine the optimal ratio of 95% ethanol to sample. We identified optimal collection protocols for fecal samples (storing a fecal swab in 95% ethanol) and saliva samples (storing unstimulated saliva in 95% ethanol at a ratio of 1:2). Storing skin swabs in 95% ethanol reduced microbial biomass and disrupted community composition, highlighting the difficulties of low biomass sample preservation. The results from this study identify practical solutions for large-scale analyses of fecal and oral microbial communities.IMPORTANCE Expanding our knowledge of microbial communities across diverse environments includes collecting samples in places far from the laboratory. Identifying cost-effective preservatives that will enable room temperature storage of microbial communities for sequencing analysis is crucial to enabling microbiome analyses across diverse populations. Here, we validate findings that 95% ethanol efficiently preserves microbial composition at room temperature for weeks. We also identified the optimal ratio of 95% ethanol to sample for stool and saliva to preserve both microbial load and composition. These results provide rationale for an accessible, nontoxic, cost-effective solution that will enable crowdsourcing microbiome studies, such as The Microsetta Initiative, and lower the barrier for collecting diverse samples.

      Gut Health Test

      How fresh does the poop sample need to be for analysis?

      For dogs, we recommend collecting a sample as soon as your dog poops, picking it up in a bag, and bringing it to your sampling area right away. For cats, the sample should be less than 8 hours old.

      Do I need to discontinue supplements or medications before taking a poop sample for analysis?

      When possible, we recommend discontinuing antibiotics and probiotics at least 24 hours before taking a poop sample for analysis.

      My pet is having diarrhea. Can I still send a poop sample for analysis?

      Yes. Our test has been carefully optimized to account for loose stool or diarrhea. When you collect the sample, try to cover as much of the swab tip as you can, and be sure to break off the swab tip and leave it inside the tube.

      Will my pet’s sample be safe in the mail?

      The sample tubes included in the test kit contain a special preservative that keeps the bacteria in your pet’s sample well protected at a wide range of temperatures for up to a year. We have received, and successfully analyzed, fecal samples shipped from 6 of the 7 continents. We recommend sending the tube(s) soon after you collect a sample, but the sample will be safe during transit.

      Gut Restore Supplement

      What is the Gut Restore Supplement?

      The Gut Restore Supplement ( fecal transplant in a capsule) provides a whole community of healthy cat- or dog-specific microbes that are sufficient to build a healthy microbiome and restore balance.

      Why are some of my Gut Restore capsules different shades of brown?

      The Gut Restore Supplement is a natural product that is gently preserved and processed. Small variations in diet, hydration status, or activity can result in capsules that are slightly different colors from one another.

      Do the Gut Restore capsules need to be given whole, or can I break them open and mix them with food?

      Whenever possible, the capsules should be given whole, and should not be opened. This is because the outer capsule has an acid-resistant coating that protects the bacteria during their journey through the stomach. Without the outer capsule as protection, the bacteria may die in the stomach.

      Gut Maintenance Plus

      What are the ingredients of the Gut Maintenance Plus supplement?

      The active ingredients of the Gut Maintenance Plus supplement are: Saccharomyces boulardii ; Bio-MOS (Mannan Oligo Saccharides); PreforPro: LHO1- Myoviridae , LL5- Siphoviridae , T4D- Myoviridae , LL12- Myoviridae.

      The inactive ingredients are: Inulin from Organic Jerusalem artichokes; Rice Hull; Rice Bran; Medium-chain Triglycerides (MCT). Capsules contain modified cellulase, pectin, and water.

      What is the shelf life of the Gut Maintenance Plus supplement?

      From the time the Gut Maintenance Plus supplement is shipped, there will be at least 3 months of shelf life remaining.

      How long should my pet take the Gut Maintenance Plus supplement?

      The Gut Maintenance Plus supplement is intended for intermittent (on and off) use. On an ongoing basis, it is safe to use for up to 60 days at a time.

      Oral Health Test

      When is the best time to take an oral sample from my dog?

      The best time to collect a sample is first thing in the morning, before feeding your dog. Food particles can contaminate the sample and make the results less accurate.

      Introduction

      Bacterial samples are critical for research, diagnostic, and teaching purposes. Although there are many ways to store bacteria, the ideal method is a function of bacterial compatibility, experimental purpose, and cell viability. As a general rule, the viable storage period of bacteria increases as the storage temperature decreases. Once the temperature is below the freezing point, however, cryoprotectants are essential to reduce cell damage caused by the freezing process.

      The specific length of time that a culture will remain viable in a given storage condition is dependent upon the bacterial strain. Cell death during storage is inevitable but should be minimized as much as possible, which can sacrifice ease of use. Bacterial cultures that are used regularly (i.e., daily/weekly) can be stored on agar plates or in stab cultures in a standard refrigerator at 4°C. If cultures will not be used for more than a few weeks, though, more long-term storage methods should be considered for maximum bacterial viability (Table 1).

      Short-term storage

      Working bacterial stocks can be streaked onto agar plates and stored at 4°C for daily or weekly use. Culture dishes should be wrapped with laboratory sealing film (plastic or paraffin) and stored upside down (agar side up) to minimize contamination and to keep both the culture and agar properly hydrated. Some bacterial strains can be stored for up to 1 year at 4°C in agar stab cultures, which are especially useful for transporting samples to other research facilities. Stab cultures are prepared by first sterilizing strain-compatible agar (e.g., lysogeny broth [LB] agar for E. coli) and then transferring the warm liquid agar to screw-cap vials using the appropriate aseptic technique. After the agar has solidified, a single colony is picked from an actively growing culture using a sterile, straight wire. The wire with the bacteria is then plunged deep into the soft agar several times, and the vial is incubated at 37°C for 8–12 hours with the cap slightly loose. The vial is then sealed tightly and stored in the dark at 4°C.

      Table 1. Approximate time bacterial cultures remain viable in different storage conditions.

      Long-term storage

      As mentioned above, the temperature at which frozen bacteria are stored affects how long they can be stored while remaining viable. Freezing and thawing cells at an appropriate rate and maintaining the frozen stocks at the proper storage temperature help to minimize damage from the freezing process. Also, the greater the cell density, the better the recovery is after thawing the cells. For most bacteria, a density of 10 7 cells/mL will result in adequate recovery if all conditions are properly maintained. 1-2

      Cryoprotectants: As water in cells is converted to ice, solutes accumulate in the residual free water. This localized increase in salt concentration can denature biomolecules. 3 Furthermore, ice crystal formation can damage cell membranes. Additives that are mixed with the bacterial suspension before freezing lower the freezing point and protect cells during freezing to minimize the detrimental effects of increased solute concentration and ice crystal formation. The most commonly used cryoprotectants are dimethylsulfoxide (DMSO) and glycerol, which are typically used at 5–15% (v/v). Non-permeable additives used as cryopreservants, such as polysaccharides, proteins, and dextrans, adsorb to the surface of microorganisms and form a viscous layer that protects membranes, making these agents particularly useful for cryopreservation. Other commonly used additives include blood serum, ethylene glycol, methanol, skim milk, yeast extracts, and tripticase soy. 4

      Freezing samples: To prepare glycerol stocks, the glycerol is first autoclaved and allowed to cool. The appropriate volume of glycerol is added to a suspension of log-phase bacteria and vortexed to dissociate the cells and ensure even mixing of the bacteria with the glycerol. After aliquoting the suspension into cryogenic screw-cap vials, the cells are snap-frozen by immersing the tubes in either ethanol-dry ice or liquid nitrogen and then stored in freezers (‑20 to -80°C) or liquid nitrogen (-150°C). 5 Repeated thawing and refreezing of the bacterial stocks will reduce cell viability and should be avoided. When recovering strains with antibiotic selection markers, culturing them on selective media will ensure that the bacterial stocks were not contaminated.

      Freeze-drying: Bacteria can be freeze-dried by suspending log-phase cells in a lyophilization medium and then freeze- drying the suspension. Not all bacteria can be successfully freeze-dried. 6-8 Certain strains might not survive the process or die rapidly once freeze-dried. The best way to determine if a strain is amenable to freeze-drying is to empirically evaluate its stability post–freeze-drying while maintaining a live culture as a backup. Once freeze-dried, it is best to store the bacteria at or below 4°C.

      In large animal medicine, parasite resistance has become a serious issue in several species ranging from horses and cattle to small ruminants. In order to best serve our clientele, proper recommendations with regard to parasite management is essential.

      Veterinary technicians routinely perform fecal examinations to assist the veterinarian in making a proper diagnosis so that he or she can prescribe the anthelmintic(s) needed to treat parasite infestations. Unfortunately, parasites are becoming increasingly resistant to several classes of these medications.

      By performing two quantitative Fecal Egg Counts (FEC) using the Wisconsin Sugar Flotation Technique on an animal’s feces the day of treatment and 10-14 days after treatment with an anthelmintic, valuable information can be obtained. Five grams of fresh feces are needed and the feces must be tested within 48 hours of collection. This test is used to determine an animal’s worm burden in eggs per gram (EPG) of feces.

      For horses, the client should collect one “apple” of feces so there will be a sufficient sample size for testing. Furthermore, all horses at the facility should be tested.

      For cattle, the technique is the same. However, the test may be performed on a pooled sample of 20 animals. The twenty samples should be collected from random animals in the herd. The second samples do not need to be collected from the same animals. This allows the test to be performed at an affordable price as individual animal tests are not cost effective. The client should submit samples of at least 5 grams each in individual containers.

      The results of these tests provide valuable information for the veterinarian to determine if treatment is necessary and whether resistance is developing to the anthelmintics used on that farm.

      To perform the Wisconsin Sugar Flotation Technique, place 3 grams of feces into a paper or plastic cup. Then, add 10 ml of Sheather’s solution (Sheather’s solution is made by adding 454 grams [1 lb.] of sugar to 355 ml of hot water and stirring until dissolved. Allow the Sheather’s solution to cool prior to use and store in the refrigerator.) Mix the sample thoroughly. Place a funnel into a 15 ml centrifuge tube. Next, place a strainer into the funnel and pour the mixed solution into the strainer. Be sure to squeeze out any liquid remaining in the strainer using a tongue depressor. Centrifuge the test tube for 2-4 minutes. Then, fill the tube with Sheather’s solution until a meniscus forms. Place a coverslip on the meniscus. Let the coverslip set for 5 minutes, and then place it on a slide. Count all eggs under the coverslip using the 10x objective on the microscope. Once all of the eggs are counted, take that number and divide it by 3 to determine the eggs per gram (EPG) of feces.

      Please note that when performing a FEC in horses, strongyle and ascarid eggs are counted separately. Other parasite eggs are not counted but should be noted in the results.

      To perform a FEC Reduction Test (FECRT) a fecal egg count should be performed on Day 0 and again on Day 10-14. The FERCT helps the veterinarian determine the efficacy of the anthelmintic that was used.

      EPG (Pre-Treatment) – EPG (10-14 days Post Treatment) X 100= % Egg Reduction

      A FECRT of 90-95% means the parasite treatment was efficacious while a FERCT of less than 90% indicates resistance.

      When performing a FEC, it is important to remember that the number of eggs in the feces of ruminants varies by season. Many parasites go into developmental arrest during winter in the northern states and during summer in the southern states. So the best time of year to perform a FEC would be April through July in the northern states and December through March in the southern states. In horses, the FEC can be performed any time of the year.

      In summary, the Fecal Egg Count Reduction Test using the Wisconsin Sugar Flotation Technique is simple to perform, will provide your veterinarian with a wealth of information, and adds value to your practice.
