Taxonomy & functions

We use functional profiling along with relative abundance to determine the microbes functions: what they’re actually doing in the body.

Species detection

Each sample screens for 120,000+ bacteria, viruses, fungi, and protozoan parasites– down to a 0.05% relative abundance.

CLIA-CAP certified

All Tiny Health tests are processed in a US Based CLIA-certified and CAP-certified lab, assuring the highest quality standards.

Shotgun sequencing

Through metagenomic sequencing, Tiny Health uses the nucleic acids in microbial DNA to identify all microbes present in the sample.

The PRO Gut Health Test Includes both:

Microbial shotgun sequencing

  • Relative abundance
  • Microbial functional capacity
  • Gut inflammation index
  • Health condition signatures
  • Actions for rebalancing, restoring and optimizing gut health

Non-microbial stool chemistry

  • Digestion/absorption markers: Elastase, fat stain, carbohydrates
  • Immunology: Secretory IgA
  • SCFA concentrations: Butyrate, acetate, propionate, valerate
  • Inflammation markers: Lactoferrin, lysozyme, calprotectin
  • Intestinal health markers: pH, beta-glucuronidase, occult blood

Who should take the PRO test?

Adults with a history of GI issues or a new issues - the PRO kit inflammation markers can help to identify microbial and non-microbial sources of gut inflammation, helping to better pinpoint root causes of symptoms

For those with symptoms related to food, or for those wanting to optimize nutrition, the PRO kit digestive-related insights can help tailor next steps based on their personalized results

 For kids 3 years and older with atopic conditions*, the PRO kit can help assess if digestive function could be part of the issue or if inflammation from food exposures is showing up in the gut

For anyone with multiple food sensitivities, the PRO kit can illuminate how the immune system is responding through sIgA measurements, as well as digestive and absorption functions

*The non-microbial insights in the PRO Gut Health Test  reflect reference ranges for 3 years old and above. For testing under age 3 use a Tiny Health Gut Health Test

For women with PMS, who are perimenopausal or experiencing other hormonal-related symptoms - assessing beta-glucuronidase is key. This enzyme can play a role in estrogen levels and is a detoxifier. Beta-glucuronidase can influence how medications and environmental toxins are eliminated from the body.


With the additional PRO Gut Health Test insights you'll be able to:

Non-microbial test

Harness the full potential of a healthy diet

  • Understand if food is being absorbed with stool fat and carbohydrate composition
  • Assess impairments in digestive functioning with enzymes like elastase and SCFA concentrations
  • Illuminate contributing factors to symptoms or underlying causes of nutritional deficiencies
Non-microbial test

Assess colonic inflammation and gut barrier function

  • Measure gut inflammation directly with immune cell derived inflammatory markers
  • Monitor changes in inflammatory gut conditions with markers like lactoferrin and calprotectin
  • Assess immune system potential to protect the gut with secretory-IgA and lysozyme

Pro kit metrics
Non-microbial test

Monitor gut metrics related to health

  • Assess microbial contribution to detoxification and metabolism of hormones, medications, and environmental toxins with beta-glucuronidase
  • Build resilience by establishing a healthy gut pH
  • Identify areas for additional follow-up with occult blood

With the microbial shotgun sequencing test you’ll get:

Functional insights

Condition related insights

  • Assess the capacity of the microbiome to perform different functions from digestion of HMOs, fibers and complex sugars to production of SCFAs
  • The most specific dietary and supplement recommendations tailored specifically to your patient's needs
  • Identify microbes that frequently show up in common vaginal infections, such as bacterial vaginosis and yeast infection.
  • Build resilience in the vaginal microbiome to reduce recurrent infections with evidence based recommendations

“Tiny Health has been an invaluable tool for my own children and the families I see in my clinical practice. To know exactly what is going on in the gut helps drive evidenced-based interventions that create real health changes. I can't say enough good things about this company.
Dr. Joy Eberhardt, MD, FAAP
Gut improvements from the focused recommendations have assisted many of my patients with reintroduction of foods that were once problematic. The test results have been very reassuring to several of my patients, helping ease parental anxiety.
Dr. Annelise Huntzinger, DO
I appreciate the intense detailed picture of the microbiome that the Tiny Health test provides. Understanding the balance of strains present and lacking helps me to ensure holistic treatment for infants experiencing gas, colic, reflux and non-IgE allergies.
Robyn Price, RD CBS
