The sign up process was easy. The blood draw tech was great. Hope that you will consider approving a lab in my home town of St. George UT so I don't have to drive to Vegas for my testing.

I really appreciate what Function offers. Through consistent lab work and following their recommendations (diet, supplements, etc.), I have drastically improved my health. My cholesterol has dropped; I am no longer prediabetic. So much positive from simply committing a little money for labs and adjusting my diet to achieve a better tomorrow.

I love getting the indicators that help me regulate my health with my doctor. My insurance will not pay for many of these tests and they are critical for understanding the whole picture.
