What are stool testing options?

There are several stool testing options discussed in the “Huberman Lab” podcast episode featuring Dr. Sara Gottfried. Here are the key options mentioned:

1. Genova One-Day Stool Test: This test requires you to collect one day's worth of stool and send it to a lab in North Carolina. It's recommended if there are no specific concerns about parasites.

2. Genova Three-Day Stool Test: This is recommended if there is a concern about parasites, especially for those who travel frequently to places with a higher risk or for those who experience gut symptoms. It involves collecting stool samples over three days.

3. Thorn Gut Bio Test (by Longevity): This test is AI-powered and designed by a PhD specializing in deep phenotyping and bioinformatics. It's particularly noted for its dense data but is marketed towards those who enjoy in-depth analysis. Unlike the Genova tests, the Thorn test uses a wipe method instead of requiring the user to dig through their stool. However, one point of critique is that the recommendations from this test tend to promote Thorn's supplements 1.

These options vary in their convenience, the depth of data provided, and their associated costs. Dr. Gottfried recommends the appropriate test based on individual needs and circumstances.
