I was curious about the biomarkers and now knowing the test results I can try to improve my health. I thought I was doing everything fine to stay healthy, but now I know that it definitely needs some improvement. Thank you Function Health.

I don't have a good sense of what I need to do or what my issues are in plain English. Not sure the value is there for the money and not sure what the membership really buys me.

The staff was nice and professional. However, the small closet lab at the back of a grocery store is terrible. Lots of excess "stuff" everyhere. Bathroom sink and faucett needs replaced. Not impressed with the facitlity. Staff was fine.
