The whole process from start to finish has been great. I just started my 2nd year with Function and I am a huge fan. Easy to use and set up in a way that I can drill down into exactly what I need.

Very comprehensive for the price. Was able to diagnose an easily thyroid condition and begin treatment. Will be sharing the results with my Dr. The Function results are far more in-depth than my annual tests. Would recommend to anyone.

I originally gave Function a 3-Star review because I did not think my overall Testosterone level was measured, but the metric took longer to populate in my report. Function responded to my complaint was was great about it. That was my only complaint, but it was an oversight on my part. 5-Star. Very thorough.

Blood draw was smooth and straight forward. Results came back timely. It was hard to tell whether all results were in or if more were still coming. Now that the results are in, I read the comments but I don't really know what the next step is. I feel a bit lost in the process. I was expecting that recommendations and action plans (perhaps with AI) would be next. I hope that we can sort this out to know where to go from here.
