Thank you for trusting us with your health. Every review helps more people discover what’s possible with Function.
Overall, an informative experience. I think it’s pretty good value for the price, the feedback is thorough once the lab results come back. One observation- the number of vials of blood drawn is too much for some of us smaller people to do in one visit. I had to break up my annual into 3 blood draws, for a total of 16 vials of blood. It took several email and AI chats to organize the situation - which could have been resolved with one phone call, but not once was I offered that option nor is there a number anywhere for us to get a hold of a person. Please improve this process for future users, it was rather cumbersome and frustrating.

Thank you for sharing your experience, Laurie. We’re so glad to hear the process felt easy and that you received your results quickly.
I really like the testing and the info supplied subsequently. What I cannot tolerate is the fact that many tunes in explanation they used noncurrent meds from my history to make suggestions. I have been discussing this with the concierge. I finally removed all history from my records but how is that helpful overall? Update: I received a reply. There are no more references to my past meds. I’m glad I signed up. Enjoy the app too.
