Mike
I live in AZ and have had a hard time scheduling. I was able to complete my follow-up testing with help from a concierge. However, I paid for additional testing and have not gotten very good support from the Function concierge team in scheduling those tests. At this time the concierge I was communicating with has been unresponsive. My initial testing experience was fantastic, the second experience has been more than underwhelming.
Response from Function HealthJul 16, 2026

Our team has let us know they were able to assist you directly with scheduling, and we appreciate you bringing your concerns to our attention. Your feedback helps us continue improving the member experience.
Bette S.
I did my first 100 biomarker testing and was impressed with how quickly the results came back. The report is very detailed. This will be very helpful with making sure I’m on the right track with my supplements and my medications. I plan to find a functional medicine group that can help decipher the report.

Donna
The process for blood collection at Quest is very easy. I am very pleased that the lifestyle changes I have made as a result of your clinical recommendations are reflected in my improving results. I still have improvements to make but I can see how monitoring more detailed results can really make a difference.

Eric
Simple sign up, and scheduling for labs. Results all back within 8 days with the UA next day. Clinical notes within 9 days of labs. The only thing I need is an MRI CLOSE TO ME. I’m in the largest city in Alabama so I supposed there’d be one here, Function Health did refund the MRI since there wasn’t one close though.

Don P.
Everything was so smooth. East to order tests and schedule. Quest was on time. Results came back quickly. Troupes were easy to read.

Darrell J.
Very efficient and rapid turnaround. Great test panel, with clear explanation of results. My only suggestion is to have local nurses take blood work at home, or expand network of labs so I don’t drive almost 100 miles round trip.

I have been super impressed with the level of data and information Function Health gives in addition to the bloodwork results. It really does put the information into the individuals hands to have a positive impact on their own health. I have been recommending the company to my freinds and family.
