Life-saving discovery of elevated blood mercury plus other clinically significant abnormalities not usually tested made me a true believer.

Function is so incredibly speedy in their processing. I am obsessed with checking the portal. It's been a game changer. The clinician notes are incredibly insightful, maybe sometimes a little hard to translate from doctor-ese, but I get it. This is the most invaluable tool and I cant stop talking about it. I am so hopeful about why I have the issues I do when no one has been able to help me to date.

I love the full explanations of each test. What it means and how to fix it. I love that it is on an app that I can review at any time.

Function Health has been a real game changer in my journey toward optimum health. Doctors don’t routinely run most of the blood markers that are included in the Function Heath menu. I was able to identify and correct certain issues that needed my attention that were never identified by my annual exams or previous blood work. I highly recommend Function Health to anyone looking to take take responsibility for their own health.

Great experience so far with my first year with Function Health. Great communication from the staff/website and awesome clinician interpretation of my results. So thankful to have the opportunity to take charge of my own health through Function and monitor my own bloodwork along with professional interpretation.

I really appreciate being able to see the tracking of my health history over the years in an easy to read and understand way. Have always had a great experience with the draws- seemly process, even if having to go in as a walk-in. Great customer service and comprehensive reports after the results are factored!
