The gut microbiome resides in your large intestine and is host to more than 1000 species of bacteria that perform certain important functions from shaping the immune system to influencing metabolism of nutrients to fortifying the intestinal mucosal barrier.
It is important to know the abundances of the bacteria that symbiotically live in the human gastrointestinal tractbecause imbalances in the gut microbiome may lead to gastrointestinal symptoms, skin conditions, autoimmune disorders, immune system imbalances, and multiple inflammatory disorders.
The Vibrant Gut ZoomerTM report provides you with actionable recommendations that include potential risks for:
- Intestinal permeability (SCFA producing bacteria and tight junction integrity)
- Intestinal disorders (IBD related bacteria)
- Heart health (inflammationinfluencing and TMAO-related bacteria)
- Autoimmune disorders (celiac, Crohn’s, rheumatoid arthritis, etc)
- Metabolic disorders (Obesity, diabetes, etc)
- Nutrition (Vitamin production, oxalate metabolism)
- Intestinal parasites including Cryptosporidium, Entamoeba and Giardia
- Fungal yeast overgrowth from Candida albicans
The test performs the most comprehensive analysis available of your intestinal microbiomeecosystem from a simple one-time stool collection. This test examines the complex and intricate relative abundance of each species or genus measured, in relation to the rest of the ecosystem, to provide a unique perspective on the gut microbiome and its connection to disease and inflammation.
The Vibrant Gut ZoomerTM also provides patients with an actionable report that includes dietary recommendations and other natural supplementation like prebiotics, probiotics, and polyphenols.
The Vibrant Gut ZoomerTM is the most comprehensive gut microbiome test available on the market to clinicians, including over 100+ species and genus-level measurements, as well as phylum assessments and diversity index.

Should I stop probiotic supplements before taking a Vibrant Gut ZoomerTM sample?
The Vibrant Gut ZoomerTM measures microorganism 16sRNA from a person’s stool sample. The results reflect the relative abundance of these microorganisms (bacteria, candida yeast, parasites, and viruses) compared to a reference range at the time of the sample. Thus, if a person is using a probiotic supplement the days/weeks leading up to the sample collection, their sample will reflect the ecosystem as influenced by the probiotics.
Our practitioners usually like to use the Gut ZoomerTM in one of two ways. They will either have the patient remove or discontinue the probiotic for ~2 weeks before sample collection. The sample will then represent a person’s “baseline” microbiome ecosystem and a practitioner can individually recommend probiotic supplementation from baseline. The second strategy would be to run a Gut ZoomerTM about ~one month into probiotic supplement to determine if that particular product is affective for that individual.
Can you tell me about the Gut ZoomerTM 16s RNA technology?
The Gut ZoomerTM is a DNA test. PCR is used to amplify and extend products of genomic DNA in the stool sample and then Vibrant’s microarray technology is used to measure bacteria 16s RNA.
Does this report show all of the bacteria that are growing in my gut?
Over 1,000 microbial species have been identified in the human gastrointestinal tract, and research is still evolving in this area. Of all the bacterial species identified, only about 100 bacterial species have been associated with potential health outcomes based on existing scientific studies published in peer-reviewed journals. The Vibrant Gut ZoomerTM measures those species identified as having the greatest impact on health and disease.
Are there other types of bacteria that may be causing symptoms that are not on this report?
The Gut ZoomerTM looks at three different types of dysbiosis:
- dysbiosis caused by a lack of good flora
- an overgrowth of bacteria that could be considered opportunistic
- a lack of diversity in the types of flora found on the sample.
In the process of putting together a clinical history that takes into account your symptoms, the Gut ZoomerTM test provides multiple correlations/risk factors for certain disease states or metabolic abnormalities. Because this type of testing is still an emerging science, it could be that your symptoms are not explained by the bacteria found on the report, however, since the test provides disease and metabolic associations for ~105 bacteria, this is rare.
Does the check mark on the Gut Pathogen test indicate that the pathogen is present?
The check mark indicates that the pathogen has been detected in the sample at a level that is considered pathogenic. See Vibrant’s validation report that states limit of detection (LOD) for each pathogenic organism.
Does the Gut ZoomerTM test for Candida?
Candida is included on the expanded Gut Zoomer Completepanel.
Does the Gut ZoomerTM test for SIBO?
No. A stool test is never determinate for SIBO, as stool testing evaluates large bowel microorganism ecosystem and SIBO is a manifestation in the small bowel (SIBO = Small Intestinal Bacterial Overgrowth). However, there is a correlation with an overabundance of certain bacteria that are associated with SIBO. If SIBO is suspected, the provider should complete an extensive intake and review of symptoms and consider running Vibrant’s IBSSureTM which includes anti-CdTB and anti-vinculin antibodies that have a strong positive correlation with positive SIBO diagnosis.

Intestinal oxalate degrading bacteria plays an important role in maintaining oxalate homeostasis and reducing the risk of kidney stones. In this study, the oxalate degradation activities of 14 species of Bifidobacterium strains were examined, among which results indicates B. animalis carries the oxc gene, which encodes oxalyl-coenzyme A (CoA) decarboxylase, a key enzyme in oxalate catabolism which then making it a strong candidate for the prophylaxis and management of oxalate-related kidney disease.
Methanobrevibacter smithii Mark Pi mentel MD, Robert P Gunsalus, Satish SC Rao MD and Husen Zhang Methanogens in Human Health and Disease.
The review examines the impact of methanogens in human health and disease.Methanobrevibactersmithii accounts for 94% of the methanogen population. Methanogens oxidize hydrogen to produce methane and ensure more complete fermentation of carbohydrate substrates, leading to higher production and adsorption of short-chain fatty acids, which may lead to obesity. Recent evidence has linked methane production to the pathogenesis of constipation and irritable bowel syndrome (IBS), as well as obesity.
