The lab work was quick and easy and results came back surprisingly fast. I also like the detail showing normal vs. above normal and the narrative describing the concerns associated with out of range numbers.

Cindy N.
I am more than thrilled with this experience. I’ve used function health since January 2025 and have done the follow ups that go along with the initial annuals. This, to me, is how healthcare should be. These blood tests are telling me more about myself in 18 months than I’ve known in 60 years. I like that I can make adjustments through the follow up blood results. I use a functional medicine health consultant as well as a PCP. They get the results, we have conversation, I make the decisions.
