There are several outfits willing to profile your microbiome, the trillions of microbes that live in your gut, if you send in a fecal sample and pay a fee. But while you may be contributing to science, you won’t learn much about your health from the test because the field is still in its infancy, said Dr. Rashmi Sinha, a senior investigator at the National Cancer Institute. “It’s not ready for prime time,” she said.
"Can I Test the Health of My Gut Microbiota?" is from the July 10, 2017 Science section of The New York Times. It was written by Roni Caryn Rabin and narrated by Kristi Burns.
