When I first heard of this, I thought too good to be true. Did some research and yes, two sets of extensive labs for $365.00 AND review of them. AWESOME! Even with NY's own fee (of course), it was a bargain.

I take my health seriously and Function just gave me greater insight to further support my health journey. And it's so much more than just your average blood tests conducted during annual physicals. Amazing! Now I feel confident what I need to do going forward to maximize my health and feel great.

The detailed analysis did help me target some specific adjustments I can make and provide much better data to other health providers I work with. This is a big plus. I look forward to benefiting from some of the add-on tests.

I've been using Function Health for over a year now. I renewed in July and quickly regretted that decision. The first year went fine and I really liked the detailed information about my blood markers. But as the second year rolled around and I needed to schedule my blood draw the frustration began. The app said the state I live in now does not allow me to schedule on the app, I need to do it with Live Chat. Not a problem except live chat is not a human, would not work, had not idea what I was talking about and couldn't get me to a human to help. I continued to try but with no success. I had to dig to find a way to email and human that could help and that was not easy. Until they figure out their customer service or AI bot, I'd find another company to use.
