They were helpful to remind us of our follow up tests. I had some trouble sorting out the difference between included tests and Add-on elective tests. The AI assistant was responsive, and probably as good as any I've come across

Great value for all the tests that are performed. The clinicians notes are very helpful.

I love Function Health. Having extra bloodwork that most doctors do not do is wonderful!!

You guys are quick to answer my questions, but more importantly is there were more blood markers than I had anticipated, which narrowed down my health issues - huge win! Although it did take a while to have all of my results available and the doctor notes be complete, that's a nice to have, not a need to have. I started addressing the areas in question and I'm already feeling better, definitely will be referring!

Accurate test & insightful commentary. I would recommend FunctionHealth.com to anyone & everyone. I even gave a gift to a good friend. I was particularly impressed with how quickly the results came (next day). I will repeat!

This program has given me insight into my health that I would not have received through an annual doctor’s visit. They gave me guidance on how to reverse my bio markers that are out of range and it has worked. This program is life changing.

I reached out for help about an issue. I appreciate how prompt the response was. I also appreciate how helpful, informative and respectful the function team was.
