A person does not need to have a digestive condition, such as IBD or irritable bowel syndrome (IBS), to purchase a microbiome test. Testing companies say that people who want to learn more about their digestive tract may wish to purchase a test.

However, another condition such as Crohn’s disease, small intestinal bacterial overgrowth, food allergies, or celiac disease could cause increased intestinal permeability.

The company offers microbiome testing, blood sugar testing, and personalized advice from ZOE coaches. The test kit costs $294 but a person can choose to pay for this in six $49 monthly installments. People can then choose from three ZOE membership lengths:

Microbiome tests cannot diagnose health conditions. People should only purchase these products if they are interested in finding out which bacteria are in their stool.

Before purchasing a microbiome test, it is advisable to ensure that the company and product meet the following criteria:

There are two types of fecal testing that a company may offer. The first type looks for markers that may indicate illness or a condition, and the second involves extracting DNA.

Research notes that, currently, there is not enough knowledge or technology to incorporate microbiome test results into clinical care.

Microbiome tests measure the microorganisms in a person’s gastrointestinal (GI) tract. These tests can give the person an idea of the types and amounts of microorganisms in their gut. However, people who experience digestive issues should consult a doctor.

Floré also offers people who purchase a test kit the option to upgrade to a monthly membership. The company will send one test kit every 4 months, as well as probiotics that it claims will boost a person’s gut health.

Microbiome tests can identify which bacteria are in a person’s stool at the time of sending a sample. Different tests may look at several markers and send people personalized reports that suggest dietary adjustments.

Different tests may offer varying levels of analysis. For example, some tests may give a broad overview of gut bacteria. Others may offer a deeper analysis, differentiating different subtypes of bacteria.

In fact, the Food and Drug Administration (FDA) does not approve these types of home test kits. Anyone with persistent digestion symptoms should consult a doctor, who may perform a physical exam and suggest further testing.

The tests that different commercial microbiome testing companies offer may vary, but they will generally test a person’s stool sample.

However, if a person receives test results that they believe to be worrying, they should contact a doctor. A doctor will perform an examination and run tests if necessary.

Companies will send customers their stool sample test results, which will give them further information about the different types of bacteria and the other markers that were in their stool at the time of testing.

It may take a few days or weeks to receive the results. These should indicate the types of microbes in the sample and any food sensitivities that the person might have.

However, the company states that this service is not suitable for those who have Crohn’s disease, ulcerative colitis, or celiac disease.

Leaky gut, or increased intestinal permeability, is a condition in which gaps in the intestinal wall allow bacteria and other toxins to pass into the bloodstream. Researchers note that diet and stress can increase a person’s likelihood of developing leaky gut.

The cost of a microbiome home test can vary from under $100 to almost $1,000, depending on the company. Some companies offer both one-time purchases and subscription plans for people who want regular testing.

The analysis that Verisana provides compares a person’s test results with those of others in their age range. The company recommends that people interpret their results with the help of a healthcare professional.

The charity Guts UK states that the analysis that commercial testing provides may not be useful. The number and types of bacteria in a person’s stool may change from sample to sample, and some bacteria may remain on the gut wall rather than in a stool sample.

A person who orders a microbiome test online needs to mail a stool sample to the company’s lab using the testing kit’s prepaid envelope.

Additionally, testing cannot tell a person whether the bacteria are alive or dead — merely that they are present in the sample.

ZOE is currently available to those who reside in the contiguous United States, apart from people in New York, New Jersey, and Rhode Island, where state regulations mean that the program cannot run there.

Healthcare professionals may take a sample of a person’s stool and grow the bacteria that they find on it in a lab. This process should allow them to determine what type of bacteria is causing certain symptoms, such as diarrhea, and inform the treatment options that they recommend.

However, commercial testing is more likely to use DNA analysis. By extracting the DNA from the stool sample, healthcare professionals can find out the types and number of bacteria in the stool.

However, people should not use these tests to make a diagnosis. If a person has GI concerns, they should contact a doctor for advice.

After a person sends a stool sample to the lab, the company will send a comprehensive test analysis. The report reviews a person’s overall health and their joint health, and it provides recommendations for achieving health goals.

The microbiome diet aims to promote good bacteria in the gut. Learn if it works, foods to eat, foods to avoid, and the pros and cons.

More than 200 types of bacteria, viruses, and fungi are present in the human GI tract. Research suggests that these microorganisms may play a role in chronic conditions such as:

Although microbiome test results may give people more information about the type of bacteria in their stools, Guts UK states that the results will not be of any value to healthcare professionals.

People may take a microbiome test to identify the different kinds of bacteria in their GI tract. However, they should not use these tests for diagnosis. If a person has any concerns over the health of their GI tract, they should contact a doctor for advice.

People must provide stool and blood samples and send the test off to ZOE. The company will provide results after 6 weeks. People can use the company’s companion app to keep track of their test results and get personalized advice on dietary adjustments.

A person may also consider a food sensitivity test or speaking with a doctor about in-person testing. Anyone with GI concerns should contact a doctor for advice.

The United Kingdom’s National Health Service (NHS) also recommends avoiding foods that cause heartburn, such as citrus fruits and tomatoes. Also, the NHS notes that eating wheat and onions may lead to IBS.
