ARVIND G.
The blood tests etc are good - it is painful to use the results with a doctor as the results cannot be uploaded electronically to Apple health or any EHR

My experience was very positive and congruent with how everything was presented. I'd recommend Function Health to anyone who wants to go deeper into their health metrics.

John
The labs and data are great. The at home service and scheduling is terrible. They do not communicate well and have address errors. This caused them to not come the day they were supposed to. Frustrating when you’ve done all your prep. I’d highly recommend scheduling at Quest vs. using their at home service.

It is nice to have labs my physician won't order. It gives me a better guide to my health.

A routine exam doesn’t give you a true picture of what is really happening. Function Health identified the inflammation that is now finally under control.
