Accurate testing at the Lab. In depth testing. Clinic analysis was very helpful, And the app and web site was clean and easy to use. Better than going to the doctor for a 15 min Wellness exam.

I am amazed at how efficient and accurate Function Health is. The blood work results appear within 24 hours, with an explanation and summary of everything. It even allows the patient to ask questions. It's a game changer, as far as I'm concerned.

Christina
The results In my initial blood test with Function Health identified a hormone level issue that led my physician to diagnose and surgically remove a complex ovarian cyst. My physician said it was fortunate the cyst was discovered before it progressed any further.

Customer support was so fast and helpful. I needed assistance immediately before an early morning blood work appointment and they were there for me and got it done, all through text messaging no pesky phone prompts and waiting on hold. Function Health is an affordable health based membership that tests so for many health markers. The test results are put into an easy to read format and Function Health then provides a summary of the results so you can understand each test. I can now take proper steps to track my well being.

Jacqueline P, M.
I was very impressed with the wide array of tests included with my membership, as well as the option to add additional tests (no sales pressure at all) if desired at very reasonable prices. Scheduling the bloodwork with our local Quest lab was very easy and results arrived over the next 1-4 days (certain tests have longer processing times). The detailed written report that explained the results was comprehensive, informative and useful. The extent of testing goes beyond what annual physical labs offer and provide better insight into your true health status and risks. Great value. I would highly recommend Function Health.

Function health gives me a comprehensive view of my health markers and gives me the expertise I need to consistently improve my markers over time. It's a valuable tool and well worth the money spent on the front end to prevent greater expenditures on the backend.
