My experience with Function Health has been very positive. It is so easy to schedule the labs and following the instructions prior to getting labs is super easy as well. I love the results and then the feedback which I received in record time. I took note of the suggested supplements and purchased them in hope that any following testing will show improvement.

As a retired pharma rep I know blind spots in "healthcare". I had an event 10 years ago while traveling. I ended up in a Chicago ER at night. The report showed my Triglyceride/HDL ratio at 8.43. I am lucky I survived. I showed this to many Drs. in my territory. No doctor at that time knew how dangerous that was. I appreciate what you do. My ratio is now under one.
