Function HealthReviews of functionhealth.com

I was disappointed that they advertised for discounts etc that were not included if I was in NY. And scheduling was difficult. I ended up being charged close to what I would have been had I ordered them myself and put it through insurance since Quest now allows people to order their own tests ( and I am an MD)

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.

Fair at best

Couldn't see the lab location until after I paid and it turned out to be farther than I wanted to drive. Also it took almost three months to get my clinician's notes. Lastly, it wasn't disclosed to me that the add-on labs I ordered would require a second trip to the lab. I kept waiting for those results only to finally learn after messaging customer service that they required a separate blood draw.

Like everything but the volatility of biological age calculation when bloodwork results barely changed and/or improved. Better to level it out from test to test.

I’ve had a generally positive experience with Function. The appointment process was smooth, the medical team was great, and the app is well-designed and easy to use. However, I was disappointed by the gap between what was promised and what was actually delivered regarding biomarkers. The program was marketed as offering 165+ biomarkers, but only around 120 were included in my testing. That difference feels significant and should be communicated more clearly upfront. I also expected the AI functionality to be more actionable. For example, it would be helpful if recommendations could automatically translate into a shopping cart or purchase list through pharmacies or retailers, rather than requiring users to manually search for each supplement or product. Overall, the service and app experience are good, but the biomarker coverage and practical AI-driven recommendations did not fully meet my expectations. There is definitely room for improvement.

Like the extensive panel of tests and that I can take results to my doctor. Dislike that it took multiple months to receive the clinician notes to help me interpret the results--- and the clinician notes seemed to be AI generated and made up information about my medical history, so I don't trust that they are accurate.

I love how easy function health testing usually is and the information I get from it, but I wish my add on test that I ordered with my mid year testing could have been done at the same time and didn't require a second trip to complete it.
