Function Health has put me in control of my health. No need to wait for a referral or ask my doctor for blood work. I want to know where my body is…I schedule it myself. Liberation!

Holly Y.
Function Health has provided access to affordable knowledge of what’s going on in our bodies. The tests go significantly beyond what is available in conventionally ordered blood work. It’s made easy to complete at a local lab with thorough reviews by a Function Health doctor. This was my 3rd year of testing and plan on continuing to use this valuable asset in the future.

I’m in my second year of Function and have found it to be an invaluable tool for improving my health. I love that it shows not only the normal range but also the optimal ranges for many biomarkers , providing guidance on why each is important and what nutritional changes can be made to improve my health. It’s a great value and they continue to roll out new features. Highly recommend!
