It was very easy to schedule my blood work and they sent reminders, which was helpful. They results were posted quickly and I appreciated the clinicians comments

Laurie, Penny’s M.
So far it has gone well. I will know today how easy it is to get the results to my doctor and hopefully they will accept it since “they” didn’t order them. I may expand Function services depending on how compliant my doctor is.

This is great to know you can get these labs done and find out things that DR don’t or won’t test for .

Function has allowed me to take a more proactive approach to my own health. Through these regular tests, we discovered I had a genetic disorder that was just now beginning to emerge with symptoms. These symptoms are invisible to me and only detected in the bloodwork. This test has allowed me to discover this before organ damage takes place, giving me valuable time ahead.
