I have only good things to say about Function Health. The doctor’s summary/counsel is extensive and helpful in the recommendations made to improve one’s health.

Generally the results and evaluation with suggestions (feedback post lab draw) was extremely insightful with lots of great info- and the interaction with the site and concierge staff was very helpful...but unfortunately for me in here NW Montana, it was incredibly inconvenient to have to travel 4 1/2 hrs to the lab (and the same back home.) Until there is a QUEST Lab closer to our proximity I will pause and warn my clients of the time and extra traveling cost involved.

Finally I am in control of my own labs! Their app lets me view my labs and more importantly, it shows optimal ranges and not the unhealthy "normal" population. This is my third year with Function and I have plans to keep em forever. I recently had labs done at my physician's office and was so annoyed when I didn't have access to view them. Instead they required me to schedule another costly visit. You might think $365 is costly, but it isn't. Unlike with insurance or as a cash payer you know up front exactly the charge-no surprises here. And, I am in control, I get the labs I want. There's no medical professional telling me "that lab isn't necessary". Go for it! I've successfully had five friends and family join and they love it too!

Easy, thorough descriptions of labs and loved the clinician notes. Got the labs I wasn't able to get from my physician and now I got a referral to specialist I was hoping for.
