This is my 2nd year using Function Health. I find its a very easy process to get a multitude of blood tests at an exceptional price to keep a check on how my body is doing. I really appreciate the explanation that is provided for each test result once they are analyzed.

I loved how in-depth all the blood work was and how I can ask the AI coach for assistance and how the clinician reviewed my blood work and gave an analysis of everything. It’s important for everyone to be on top of their health. Great service!

Highly recommend. I learned about some high risk areas I was unaware of. Things I would never have known about because my doctor does not test for them. Now I have been able to start addressing these risks, along with the help of my doctor.
