The level of detail and number of biomarkers are incredible. I’ve had blood work done many times but never to this depth and have never had all the information of what it all means if it’s high or low or what the effects would be. This is an incredible service, tremendous value and has helped me find issues I had that I didn’t know existed.

Communication was great on the website and app. Loved the reminders about week, 3 days before, 1 day before the test. I also like that it was easy to see the new results and the review once everything was completed. The only thing I wish I could do is be able to print my protocols and my test results to give to my doctor. It says I need to control print but it doesn't work. Overall - great experience and feel I'm giving information to improve my health and wellbeing.

I appreciate the test results come back quickly and how Function ties it all together. I wish the 6month follow up contained all the labs I need to retest vs having to add them on at additional cost. The MRI scan lab was very professional and the bag, socks, Jammie’s were a nice treat!
