I can’t say enough good things about my experience with Function Health. The testing process was simple, and the insights I received were incredibly detailed — far beyond a typical doctor’s visit. The dashboard made it easy to understand every marker, what it meant, and how I could improve it. For the first time, I felt like I had a blueprint for my health, not just a list of numbers. The best part was how actionable everything was. Instead of vague advice, the recommendations were clear and customized. I learned more about my body in one test than in years of checkups. I also appreciate that the team communicates so well — responsive, kind, and genuinely invested in helping you thrive long-term. Function Health is absolutely worth it. It’s one of the best investments I’ve made in myself.

Very pleased with all the labs and the explanation provided on results! Also - I was not able to get the documents in the app to send to my provider so the Function Health team emailed me the documents! Very good experience and I highly recommend everyone use Function Health to get such in depth information on where your health is at!

Ease of making an appointment with Quest was great. Responsiveness of customer service team was solid. Results and clinician's notes took 3-3.5 weeks, which seemed long. Once results were obtained, I would have liked to have been able to connect with a Function Health approved biohacker (someone like Mark Hyman or Gary Brecka) to go over my results on the phone and suggest a supplementation plan alongside all the supplements I currently take (for a fee of course). The written summaries for each biomarker, while helpful, weren't robust enough to understand holistically how the entirety of results would be affected thru supplementation, lifestyle change or nutrition.

I got an idea of my overall health, and know what i need to improve. Unlike normal office visits, Function Health is not truncating my health lab results on just one organ, or system, and it is easier to understand how systems interact, therefore getting closer to the root cause, vs looking at effects.

Really easy process. Took a bit longer to get results than expected. Very pleased with the info I received. Quite educational. Appreciated the thorough explanations of each test, result, recommendation, etc. Wish there was an easier way to share with my primary care physician. What I saw was not user friendly. Would like to share exactly what I received with my doctor in similar format.

I’ve been very happy with Function Health. I had 155 bio markers tested and 12 were out of range. After repeat testing, one is improving. Still working on the others. Many of these tests were impossible to get down my regular doctors. I appreciate being able to test my areas of concern, by adding specific blood tests. It was convenient to schedule at a nearby Quest Lab. Function Health’s summary of results and recommendations were helpful. My husband recently decided to do this for himself, as well. I highly recommend.
