Real added value so far I’ll need to do the mid year test to see if the recommended plan works. Looks very promising as of now.

Selly V.
My daughter convinced me to sign up and order my blood work for function health. This was the best decision ever! Although it is expensive and not covered by insurance if you truly want to advocate for your personal health then get in control and check yourself through function health. You will not be disappointed.

Function Health made getting bloodwork done easy. Set the appointment, they send reminders to prep for the appointment, then go. The hard part is finding a regular doc to actually respond to the results. Easy peasy. I also like how you can track results from visit to visit to see how you are doing.
