Its all AI no human Dr reviewing

When you flag that the summary of your blood work doesnt make sense - there are no humans to address it - you get AI pretending to be human messaging you and telling you - you can book an appointment and when you tell them when you're free to talk - the AI can't handle it and cant respond. So your summary is wrong and there are no humans involved or they are really bad employees who should be fired.

Not Built for Women!!

Update: nearly two months later I still haven’t been able to get the cycle tests. Labs aren’t open on weekends and walk in only. Very difficult to drop everything to go wait at quest and hope to be seen. Customer service confirmed they prioritize people with appointments.

I really wanted to love Function Health because the concept is great, but my experience with has been disappointing.

If you have irregular menstrual cycles, it doesn’t seem like they have a clear process for handling it. I had to repeatedly explain my situation, and instead of addressing my actual questions, I kept receiving canned responses that didn’t apply. I was passed between multiple agents, and each one seemed to respond without reading the conversation history.

My questions were about how my lab orders had changed, but I repeatedly received generic explanations about hormone testing that had nothing to do with what I was asking. For a premium membership, I expected personalized support and continuity, not to start over with every new agent.

The testing itself may be valuable, but the customer experience needs significant improvement—especially for members with irregular cycles. This common situation was clearly an after thought. A clear SOP for these cases and better continuity between support agents would make a huge difference.
