Great experience. Tests run were very thorough. This is my second year to use Function Health. Nice to see comparison from last year to now.

Lisa H.
I’ve been a member for 3 years. Overall I’m very happy. I wish there was a way to ask specific questions after results come in and get answers from the online doctor that summarized the results. And it would be nice to be able to add my doctor to my account so results automatically get sent to her. But I would recommend Function Health to other. Very valuable info for a reasonable price!

Paige
I love the proactive approach function health allows you to take with your health. The visibility these tests and your platform give you into your overall health goes above and beyond what a doctor would do at your annual physical for a fraction of the price.

Carol
The reminders were not pushy, but once I finally made the appointment to go get my blood test done, they were good with reminders and instructions
Response from Function HealthAug 9, 2026
Thanks for sharing, Carol. We’re glad the reminders felt helpful without being overwhelming and that the instructions made it easy to prepare for your appointment. We appreciate your feedback!
Linette
Scheduling the tests was easy and I was extremely pleased to get results in 3 days. The clinician notes and action plan really help me to go forward with my healing. I was hesitant to subscribe to a plan that uses AI rather than having the ability to pick up the phone and talk to a person but I have come to appreciate the instant availability to information, and the fact that all my information is reviewed and incorporated into the responses.
Response from Function HealthAug 9, 2026
Thank you for sharing, Linette. We’re glad scheduling was easy, your results arrived quickly, and the Clinician Notes and action plan have given you helpful information for your next steps. We also appreciate your thoughtful feedback about the platform experience.
