I love Function health! The results start coming in right away, even as soon as the next day. Its so fun to have them coming in throughout the day and then I use AI to get them interpreted from a functional, naturopathic perspective. Its very empowering and more than worth the money!!

It was an easy process through Quest to get the blood draw. Also I wanted to make sure that I didn't have any autoimmune disease as I had a previous test that showed elevated ANA so I did add on the autoimmune markers labs. All of the additional test results were very informative and worth the price.

The scheduling, lab draw and payment was easy and efficient. In my situation Quest laboratories was used which is where my MD sends me anyway. The results started compiling the following day - each with detailed explanation and directives (which always linked back to my lifestyle)! Could not be more please! 10 out of 10 recommend and have been doing so!
