I have really been amazed at how much more I know about what’s happening inside my body. Great experience. However, my second time testing did not cover all of my original results ( minus add-ons) . I was under the assumption that all of the original tests were repeated the second time. Kinda disappointed, as that was not indicated when I first tested

I appreciate all of the testing that is available and the Clinician Notes you provide after testing. This is much better information than I receive from my primary doctor. I wish there was a Function Health doctor in my area!

After several weeks, of hearing nothing, I finally got my results. I guess I was ecpecting more.
