Quest Lab was very easy & fast results. Downside limited contracted sites for these labs in MT. I was easily able to do both draws while traveling in Seattle & CA bay area.

Thanks for the thoughtful review, Stacey. Your input helps guide what we improve next.
A great value for an in depth report on bloodwork. Tested a lot of things I wouldn’t have known to test otherwise.

The insight I received from the clinical summary provided me the opportunity to fine tune my nutrition and supplementation to optimize my overall health. I was very pleasantly surprised at the thoroughness of the testing and clinical summary. I have encouraged my family and friends to use Function!!

Thanks for spreading the word. Together, we’re building a community taking proactive steps toward better health.
I used Function Health for two years. It was fine for the price although I could have used my own AI to review my tests. What was really irritating is that when I moved and changed email addresses I apparently missed my November, 2025 annual payment and when I went to reinstate my account in February, 2026 they had already deleted my account and I have no access to my records and cannot reinstate my account.

I got scammed. Don't let it happen to you. It's a great concept but they don't deliver. Listing all their failures would take too long. Do yourself a favor, go somewhere else. I wish I had. Buyer Beware.

I have been a member of Function for more than a year and really appreciate the depth of results I can get without trying to haggle with my doctor to get the blood work I feel is necessary to determine what is going on with my health. It's been a game changer!
