It’s always easy to book and even change an appointment. The reminders are super helpful. I’m beyond thankful for such comprehensive results.

Roz J.
Comprehensive tests were very impressive, especially mid-year. Great value for the money Reports are detailed and very self-explanatory. No medical jargon. Assessment of a test out of range was compared against other tests within the same category that were within range to rule out any concerns. Overall, I have better knowledge of my health and biomarkers compared to the 7 tests conducted by my primary physician. My physician was shocked when I showed him the tests. He was not aware this exists.

Easy to do. Sign up, make appointment for blood draw, go to the appointment. How easy can this be? My result gave me everything I needed to know since becoming post-menopuse and solutions to work on which some, I knew, so this confirmed what I was already doing to stay healthy as I age. Great service from Quest Diagnostics too.

Underwhelming … didn’t tell me anything I didn’t already know. Haven’t had any results in nearly 3 weeks and to get what I got for the price we paid … underwhelmed.

The information is valuable, and I like getting my results quickly. I think the testing round 2 could be more telling of exactly which test biomarkers are being done; for example, I thought I was getting my thyroid panel done, and it wasn't included.

I had a great experience with Function Health. The testing was incredibly comprehensive and gave me insights into my health that I had never received through a routine physical. The results were easy to understand, and I appreciated the personalized recommendations that helped me focus on areas I can improve. If you’re looking to be proactive about your health and understand what’s happening beneath the surface, I highly recommend Function Health.
