Frequently Asked Questions

What does a Tiny Health test look for?

  • A full breakdown of what we find in your gut microbiome
  • Key Insights about your gut microbiome and what they mean for your health
  • Condition Biomarkers, which may give you clues about what’s happening in your body and the risk for specific conditions
  • Associations between any symptoms you might have and your microbiome
  • Practical tips and recommendations that are unique to your test results

How does testing work? What do I have to do?

We use an at-home stool test collected with a lab-certified swab from used tissue paper.

The process is simple and, unlike other tests on the market, Tiny Health doesn’t require gloves, a spoon-like collection device, or that you handle stool directly, just a regular tissue.

Store your sample in the included container and zippered bag, then mail it back to us in the prepaid envelope included with your kit.
