We recommend function health to everyone we know. There is not a more comprehensive, cost effective, and informational health panel system available anywhere. We could not be more impressed and satisfied with them.

Trends with test results are important and I like that however some of your tests I believe are not accurate with respect to food allergies . I have done test results with quest and labcorp days apart and found significant difference. I will be redoing some test with Labcorp this week. Some of my samples were dropped in the lab and fell all over the floor.

The results came back fast! However, there was an issue with being able to see my PDF. I reached out to the Function health team and it took far too long for them to figure out that there was a problem with my urine sample. I followed up multiple times and they still didn’t realize what the problem was. Once they told me that I need to resubmit a urine sample I asked questions about what was required to give that sample and never got answers back. I would also like to see the results compared to optimal in a better format that could be a PDF copied to my practitioner.
