Hi Kathleen, thank you for your review! We're so glad to hear you found the process efficient and the health insights helpful. We appreciate you being part of the Function community and trusting us with your health.
The experience has been excellent all-around. From the blood draw at Quest to the reporting from Function Health, it's been great. The reports have been very thorough and insightful, beyond what I expected. If you are concerned about your overall health, this is an excellent investment.

Hi Jay, thank you for taking the time to share your experience. We're so glad to hear everything—from your appointment to your results and insights—met your expectations. We appreciate your kind words and thank you for trusting Function with your health.
I have requested, what I believed to be important, blood tests from my PCP and was told no. This health screening caught problems and gave me solutions and I have made several life changes. My health goals are a greater priority and annual testing gives me feedback on my progress.

The quickness of the results

Hi Nancy, thank you for your review! We're so glad to hear you received your results quickly. We appreciate you taking the time to share your experience and are grateful to have you as part of the Function community.
( Update: I am bumping up my rating from 3 to 4 stars because after this post, they reached out to me with a clarification and an apology. ) Not all the test results are in, and yet Function is behaving as if everything is done and completed by issuing the doctor’s summary and asking for a feedback on my experience. Without the clarification that they are still waiting for more data to come in, I am confused as to why they are rushing for the closure. Where are my added nutrients test results which I paid $299 for? I am still waiting since the blood was drawn only 10 days ago.if there is a mistake at the lab and my blood was not sent to the proper place for the added test for nutrients, please reissue the test so I can get the result, or refund!

Hi Linda, thank you for your review! We're so glad to hear your appointment was easy to schedule and that you received your results quickly. We appreciate you being part of the Function community.
I've gained a lot of insight into my health risks associated with high cholesterol through the lab tests that I wasn't getting through my regular doctor. I've learned through a high Lp(a) result that I'm genetically prone to heart health risks. This is enabling me to have a more productive discussion with my doctor and to advocate for my healthcare.
