The phlebotomist at Quest was great this time - found my vein on the first try and made it a decent experience.

Function health is such a great way to get a real picture of your health through so many blood tests that you just don’t get at your doctor’s office. Results quickly and then answers to any questions that you might have. It’s priceless!!!

Somewhat Informative but not that much helpful information on how to mitigate. System keeps asking me to repeat information on supplements I take even though I previously entered this is in the system. Still some bugs in the software?

Excited to take control of my health, and Function Health is central - essential - to my care! Lab work and diagnostics: Knowing can facilitate change and/or validate course corrections. Function Health is fantastic - Great selection of labs/diagnostics. I think it's a great value. I completed my initial and 6-mo lab work. For my 6-mo, I added a hormone panel - so glad I did! Between that and other abnormal labs, my results triggered me to see a doctor, and now I'm on HRT - excited about my next labs and steps forward! My 6-month labs said I'm 3.8 years younger than my chronological age: Let's see how much I can turn back the clock! Function Health gives me proof of progress! Function Health is for folks who don't have PCPs ordering routine lab work. This service is great: I highly recommend!
