My daughter and her husband bought me Function for Mother’s Day. I am not tech savvy, so was worried about how to use gift card and set up blood tests. Everything was prompted in the app. Such an easy process to give blood/urine and receive speedy results. I got results so quickly and everything explained in depth. At the end of results, a clinician explained what you should do to aid your health and how to fix. I love that you have a second group of blood tests later. You have time to make changes with your health. I have advised so many others to try Function.
