Love the detailed explanations and making it personal to me for the biomarkers and clinician notes. Well done!
Response from Function HealthJul 2, 2026
Thank you, Kelly. Personalized explanations and clinician notes that actually speak to you are core to what we do. So glad it's landing that way.
Denise
Useful information from the 1st round of tests. Wish the 2nd round had more results.
Response from Function HealthJul 2, 2026
Your words mean the world to us. We appreciate the feedback on the second round and will pass it along to our team for consideration.
Richard
Setting up the account to start first visit, schedule appointment, verification of arrival and check in was pretty simple. I think the quick response to any questions we had was very impressive. The staff was friendly and professional. On our first visit we parked on the opposite side of building. A little bigger sign with your suite number would have been very helpful. Letting us know that we had to go out side to get to your office would have made things easier. Other than finding it the first time the whole experience was great.

Got my second round results in a day- and I ordered some extra testing! Plus, a very thorough summary from the doctor. Function is a great service.

Austin
Honestly great value for all the core markers and the dashboard is nice and convenient. Was able to make some changes based on clear data. Things I thought would’ve been off were fine, and things I thought wouldn’t be a problem turned out to be subpar.

Thank you for sharing this! Knowing what's actually going on beneath the surface, not just what you assumed, is what makes the data so powerful. We're glad you were able to take action based on what you found. To 100 healthy years!
