This is just what I needed and wanted. I wish this had been around at least ten years ago. It is helping me pinpoint what I have to work on now with my doctor. Thank you.

Overall, Function Health has proven valuable not because it replaced conventional medical care, but because it expanded the scope of preventive screening, identified subtle risk factors that merit attention, and provided a more complete picture of my overall health.

I got tired of the sick care system! I was so happy when I came across function health 4 yrs ago and to put myself in the driver’s seat of my care. I get to skip the annoying and useless doctor visits followed by labs followed by return visit followed by maybe a specialist visit. Now, I know going in to PCP what I need to talk about and save myself time and annoyance. It would be great to be able to charge the annual fee to my insurance but even without it is worth it 150% for ME to know about MY body without having to justify to a doctor WHY I want to know about i.e. MY heart health.
