I loved doing extensive bloodwork thru Function Health! Very organized. Excellent education on the results and recommendations based on results. Highly recommend!

Easy scheduling and you can pay for as little or as much as you want.

I was appreciative of the extensive blood work but what I wasn’t counting on was the quest lab tech trying to frighten me about the volume of blood taken. I was not impressed by the analysis of the physician. I did show one of my physicians and he said he must not have had access to all of your chart notes as some things were not accurate for me. Regardless I didn’t really have many markers outside of normal range and it agreed with life force that my biological age was a lot younger than my chronological age. It did confirm my scrupulous diet habits, no alcohol or drugs or smoking during a life time has paid off.

Loved everything except having to work with Quest Diagnostic (substandard setting).

Quick and detailed results that gave me deeper insight to my health. I also love the approach of the supplement and food recommendations and the avoid list. The interface is user friendly, and customer service is amazing. Very satisfied!
