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 (gut 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 Gut Zoomer report provides you with actionable recommendations that include potential risks for:
- Intestinal permeability (SCFA producing bacteria and tight junction integrity)
- Intestinal disorders (IBS and IBD related bacteria)
- Small Intestinal Bacterial Overgrowth (SIBO)- related bacteria
- Cardiovascularhealth (inflammationinfluencing and TMAO-related bacteria)
- Autoimmune health (celiac, Crohn’s, rheumatoid arthritis, etc)
- Neurological health (MS, Parkinson’s, and more)
- Liver diseases (cirrhosis, hepatitis, cholangitis, and more)
- Metabolic health (Obesity, diabetes, etc)
- Nutrition (Vitamin production, oxalate metabolism)
- Microbiome and hormone connections (Beta-glucuronidase and Beta-glucosidase)
- 67 pathogenic bacteria
- 24 Intestinal parasites
- 8 viruses

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 functional digestive analytes aid healthcare providers in determining if deficiencies in digestive enzymes, bile, or other critical metabolites are root causes of gastrointestinal inflammatory symptoms.
The Vibrant Gut ZoomerTM also provides patients with an actionable report that includes dietary recommendations and other natural supplementation like prebiotics, probiotics, and polyphenols.
Only healthcare providers licensed in their state may order laboratory testing.
The Gut ZoomerTM is the most comprehensive gut microbiome test available on the market to clinicians, including over 170 species and genus-level measurements, as well as phylum assessments and two diversity indexes. We also provide recommendations for 35 commonly used probiotic products that may be appropriate based on risks determined by lab test results. Vibrant’s proprietary microchip technology allows for simultaneous detection of DNA from almost 200 species and genera of microorganisms from a one-time collection of stool sample.

Should I stop probiotic supplements before taking 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) 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 Zoomer 16s RNA technology?
The Gut ZoomerTM is a DNA test; genetic material is extracted from a stool sample. PCR is used to amplify and extend products of DNA in the stool sample and then Vibrant’smicroarray technology is used to measure bacterial 16s rDNA.
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 a few hundred of those species have been associated with potential health outcomes based on existing scientific studies published in peer-reviewed journals.
The Vibrant Gut Zoomer measures those species identified as having the greatest impact on health and disease and tests300+ commensal microorganisms and 67 pathogenic microorganisms, plus 6 known microbial antibiotic resistance genes.
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 pathogenic or 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 hundreds of bacteria, this is rare.
How are the reference ranges established for the gut pathogens?
For each microorganism tested, a limit of detection is defined. Limit of Detection (LOD) is defined as the lowest concentration of analyte in a sample that can be reliably detected. The LOD is expressed in terms of the CFU/ml or cells/ml or oocysts/ml as per the organism tested
How are the reference ranges and abundance scores for commensal microorganisms established?
Reference ranges have been established using a sample cohort of 192 relatively healthy stool samples. The cut-off for the healthy reference range is set between 2.5% and 97.5%, and the high-risk range is set to greater than 97.5%. The healthy reference range for each bacteria is individually determined and available in the Gut Zoomer Commensal Validation report in our provider portal.
Does the Gut Zoomer test for Candida?
Candida albicans is included on the Gut Zoomer pathogen panel
Does the Gut Zoomer test for SIBO?
No. A stool test is never determinant for SIBO, as stool testing evaluates the 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. The Gut Zoomer 3.0 has a specific section for these bacteria which includes both hydrogen- and methane-producing bacteria. If SIBO is suspected, the provider should complete an extensive intake and review of symptoms and consider running Vibrant’sIBSSure, which includes anti-CdTB and anti-vinculin antibodies that have a strong positive correlation with positive SIBO diagnosis, especially refractory SIBO.
Can this test tell me what probiotic supplement my patient needs?
Probiotics can play a vital role in helping to re-populate and maintain balance of one’s microbiome ecosystem. There is no one-size-fits-all approach for recommending probiotic supplements. Practitioners should individualize recommendations based on patients’ presenting symptoms and degree of dysbiosis.
The Vibrant Gut Zoomer 3.0 provides individualized probiotic recommendations for each disease state association section listed in the report, displayed in the section titled “your level of probiotic organisms.”
Vibrant presents a list of commercially available probiotic organisms that clinical literature has demonstrated to be beneficial for the specific disease-state association listed above. These organisms are also measured on Vibrant Gut Zoomer 3.0 and an individual’s abundance score for each organism is given. These recommendations and results can help a practitioner define an individual probiotic recommendation and protocol.
What should I do if my calprotectin is significantly elevated?
Calprotectin is a marker of inflammation in the gastrointestinal mucosa. Although it is not diagnostic of inflammatory bowel disease, calprotectin can indicate the possibility of Crohn’s disease, chronic ulcerative colitis, and/or the overuse of NSAID medication. If your calprotectin is elevated on the Gut Zoomer 3.0 test, you may want to schedule a visit with your gastroenterologist or discuss this finding with a knowledgeable healthcare provider.
What should I do if my pancreatic elastase is low?
Pancreatic elastase is low when the tissues of the exocrine pancreas are not producing enough pancreatic elastase and digestive enzymes. This condition is called exocrine pancreatic insufficiency and can occur when the pancreatic ducts are blocked or the pancreatic enzyme producing cells are blocked.
It is more often seen in conditions such as pancreatitis and sometimes pancreatic cancer. It is recommended you consider taking a pancreatic enzyme supplement to your regular meals as well as scheduling a visit with your primary care provider or gastroenterologist.
*Note: if you did the GZ 3.0 test with a sample of loose stools/diarrhea, your pancreatic elastase value may be difficult to accurately assess.

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.
