Routine exams/blood tests give you the basics and nothing more. I was very pleased with the in-depth results of the testing.

good descriptions of my condition and what to do about it. first draw was in my town, the second draw, that location had closed so had to drive 30 miles.

The only thing I would say is you need to be better about the referral process. I have told many people about your service, I think only one of my referrals actually gave me credit.

We appreciate you sharing Function with others, and we’re sorry for the frustration with the referral process. We appreciate you bringing this to our attention. Our team will follow up directly to look into your referral credits.
Paige O.
Function Health gave me better results than my own doctor and found a genetic disorder I wasn't aware of that could prevent a heart attack and stroke later in life. The same genetic disorder that may have killed my uncle and grandfather caused the heart issues my father experienced and resulted in major heart surgery. I'm very grateful to Function Health and a true believer.

I appreciated the insights that the testing provided. I presumed that the second round of testing (third blood draw) from the year would test all of the things from the first round (first and second blood draw). That wasn't clear to me and disappointed me.
Response from Function HealthAug 13, 2026

It from May when blood work was done to August to get my clinician notes. Unacceptable
Response from Function HealthAug 13, 2026
We appreciate you bringing this to our attention. We’re sorry the delay in receiving your clinician notes fell short of the experience we aim to provide. Your feedback helps guide future improvements.
