Function has given me a way to afford bloodwork. All of the markers that Function tests is invaluable. I am so grateful to have this available!

While the results and analysis were useful, the experience of getting my blood drawn by their partner Quest was awful. My appointment was 30 minutes late (I sat in the waiting room for 40 minutes, inclusive of the 10-min early arrival), then the nurse had to stab each arm multiple times looking for a vein, bruising me up in the process, and what should have been a 10 minute appointment took another 30 minutes. I would very much caution which Quest location you attend to get your bloodwork done.

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.

Katja
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.
Response from Function HealthAug 9, 2026
Katja, thank you for being part of Function for four years. We’re glad having access to your health data helps you feel more informed and prepared for conversations with your doctor. We truly appreciate your continued trust in Function!
