Awful testing partner

I waited the whole entire day at Quest only to send me home at 5pm without drawing my blood

Life Changing

Not only has this app given me data and knowledge that’s unlocked healthier living for myself, but it spotted a brain aneurysm in my husband that we’d never known about otherwise. That’s not living in fear. It’s living in knowledge. And the more we know, the more we can do to live a better life.

Grateful to have found this app and for all it gives us to be our best selves.

Doesn’t accept data from other testing

I’m frustrated. I scheduled the Function blood testing at regular intervals, spaced in with my annual physical. That’s two Function tests and one insurance sponsored test, evenly across the year. That strategy failed. Function will not accept the blood testing my physician did. I uploaded that data, but it’s not added to the graphs or analyses. Function can supplement to your doc’s testing work, but only if you’re willing to build your own tracking and analysis that combines the two.

Note that both Function and Physician data came from Quest. Same labs. Same testing. But the data can’t be combined.

Customer Support unresponsive

After explaining my missing test results to their AI chatbot, I got no good answer and no way to reach a human to get a real time answer. Was told someone would get back to me I. A few days. Totally unacceptable when dealing with something is important as blood test results.

UPDATE: Function Health replied with the typical “we’re very sorry, this is not how we do business, blah blah” post. BUT they still insist on an email correspondence, o phone number, not way to chat LIVE with a REAL person. For a health related company, it is inexcusable not to provide a way to reach a human in real time. STILL disappointed.
