James
The most convenient “doctor’s visit” I’ve ever had. From the online questionnaire to to the actual clinic blood work to the final health summary… everything was quick and easy.

Thank you for sharing, James. We’re glad the experience felt quick and easy from the questionnaire and lab visit through receiving your health summary. We appreciate the kind words!
Adela
Appointment was quick. The nurse was pleasant and professional. The blood draw was easy and painless. I highly recommend Function for complete attention to my health needs that I may have overlooked.

Customer service follow up is wildly slow and wildly inaccurate. Too many people not reading their counterparts notes so giving wrong information. Has not been a positive experience at all.

By getting my blood work and getting it reviewed by my doctor and myself, I have lowered my blood pressure 20 points. I’m working on my cholesterol LDL and because of your guidance it is tremendously helping.

Everything from making appointment to receiving results went exactly as described and so smoothly. Results clearly revealed and explained.

It was very detailed. Highlighting positives, negatives, and summaries. One thing I would suggest is giving more details on how to correct issues.
