I’m so glad I did this!! My son was kind enough to pay for my testing with Function Health because I wasn’t getting any answers from my doctor. This has proved that my instincts and symptoms were correct. I now have been able to formulate a plan with the help of the bloodwork and clinical notes provided by Function Health. Taking charge of my health has been an incredible experience. I would highly recommend this testing.

Ease of registration for the program and scheduling lab work; clinician notes are easy to understand for non-medical professionals like me!

I think it is a great resource for your health. It is very useful to your Doctor in directing him were the short falls are and fixing them . Bob

I have obtained so much helpful information about my health, that I wouldn't have access to normally. It was very easy to outline my goals and initiate next steps. And Function Health offers an endless amout of resources, which is important to me because there are not many functional health providers in my area. Highly recommend!
