the way the results are reported are not liked by my doctor - she prefers the way Quest does it. they are too busy to move through the way you present the information.

It was a very streamlined and clear process! I love that the interface was intuitive and clean. The only thing I would request is an option to seek meds/supplements via Function. For example: it was recommended I supplement with testosterone but my conventional doctor doesn't find a need for this and won’t use Functions test results.

Function Health has given me a much deeper look into my health and has helped me understand what things need more attention and then has offered ideas on how to improve. Best of all, I am now seeing positive results in my lab work, without pharmaceuticals! I am thrilled and very grateful!

I have really enjoyed the Function Health platform. I love the fact that I am in control of when to do lab work. I do not need to schedule an appt with my physician, and then schedule another follow-up appt. The lab results are presented in a very easy format, and the explanation for each is very clear. I have been spreading the word about this app to anyone who is interested.

Choice of local lab and time of appt were great. AZ seems to give Function some difficulty with scheduling.
