You do not perform the tests you pay for. When we call your company to say that some of the tests were missing the automatic AI is a nightmare. And when asking something by email, your response is terrible. We will never do business with you again..

Never got all my results in and can't get anybody to contact me. Paid good money for this test and was not satisfied at all.

I learned more about my health through one round of testing with Function than I have learned by going to annual visits with my primary care provider for years. I discovered explanations for how I’ve been feeling and feel empowered to manage my health moving forward. Clinician review of my lab work was detailed, personalized and easy to understand.
