It’s a no hassle way to take control of your own health. Not only are you looking for immediate risks to health, you see long term trends, and it makes you aware of your health so you monitor yourself daily.

I appreciate the in depth information provided and the recommendations given to address any concerns. As always they encourage speaking with your personal physician about your results. The testing goes much deeper than traditional medicine for a clearer understanding of your health. Highly recommend!

Patty S.
I’m on my second year of Function testing, and am impressed and thankful for the in-depth bloodwork and analysis that is provided. My ability to monitor my own statistics and look at the recommendations Function gives means I can work with my health providers to make the best choices for myself.

Signed up, scheduled my lab blood draw for the next morning. It was completed at the lab in less than 10 minutes. Within 48 hours, I had almost 90% of the results back, with the full panel of 119 biomarkers completed in less than a week. This gave me insights into my health that I would have never found relying on doctors to order preventative tests. I still have another round of testing in 6 months included but I feel like it was already worth the money! Highly recommend!

I have completed the first year of tests. The first series of draws gave me great data to work from. I made some easy adjustments to diet and supplements. Then received the mid year report and found everything that was out of range either was now in range or moved in the right direction. The blood draws were easy and the app is easy to follow and schedule everything. Great value. I have referred friends and family and I hear similar reports back.
