I have mixed feelings about Function Health. First, I genuinely believe the concept is excellent. Giving people affordable, comprehensive access to their own health data has the potential to be transformative. The testing itself was straightforward, my blood draw was easy to schedule, and my lab results were available relatively quickly. Unfortunately, my experience after receiving those results fell well short of my expectations. I waited approximately 6–7 weeks for my clinician review. During that time, I reached out to customer support around the four-week mark and was told they were still within their stated six-week turnaround time and that someone would contact me. Eventually, I was informed that attempts had been made to reach me by phone, but I have no record of any missed calls or voicemails. I never spoke to anyone. One of my results required follow-up, so rather than waiting indefinitely, I scheduled appointments with my physician to begin addressing it. In the end, the clinician report felt more like a delayed formality than meaningful guidance. What disappointed me most wasn’t the wait itself—it was the experience of feeling unsupported after the testing was complete. Function Health has built an impressive platform, but the human side of the experience didn’t match the promise. When you’re providing health information that may identify significant findings, timely communication and follow-through are essential. I still believe the company’s mission has enormous potential, and I sincerely hope they continue to improve because this model could have a tremendous positive impact. However, based on my experience, it currently feels like the technology and growth of the platform have outpaced the level of personalized care and support being delivered. I wanted this experience to exceed my expectations. Instead, I came away believing the idea is exceptional, but the execution still has a long way to go!!

The narrative was very extensive and detailed. I learned a lot about my health and strategies to improve.
1st visit the support person i messaged messed up the order, and didn’t have all the test on at once so luckily I didn’t break my fast but I had to go back in and do a second draw the same day. And it was only caught because I happened to ask the worker why the urine sample wasn’t included and had to come back out and talk to a support person to find out that it wasn’t done correctly. So luckily I caught it, but that would have been very frustrating considering I live an hour from the nearest bloodwork center and wouldn’t have been able to go back same day if I would’ve broke my fast immediately. Also, it was not made clear that the second test would not be testing all the same biomarkers. The advertising even on the website says 100+ bio markers tested twice a year, and I didn’t find anything anywhere say that that was not true until I went to go schedule my second test. But I’m sure that’s a common complaint that people leave, because it’s deceitful. There should also be a way in the app to sort your first results from your second ones. Also, every time you click a bio marker and sends you back to the top of the list and you have to scroll all the way back down to look at the next bio marker again. Also other companies have an edge over Function because they allow you to message someone to have a conversation about the results in the clinical notes and function doesn't.

Loved the experience ! I had to reschedule my lab date. Which was very easy . I was surprised of the amount of tests that were done. Which I’m very happy about. The summary was very detailed and very informative.
Highly recommend. I learned about some high risk areas I was unaware of. Things I would never have known about because my doctor does not test for them. Now I have been able to start addressing these risks, along with the help of my doctor.
I truly appreciated the 25 page clinician notes. Helped me focus on the most important concern..... and that several concerns shared common source.
Glad to have this affordable option to monitor my health.
I had my doubts, and an inkling into what it could be(from reading too much and searching for answers)yet to actually see the proof you need to help a person further their health, was awesome.
I loved how in-depth all the blood work was and how I can ask the AI coach for assistance and how the clinician reviewed my blood work and gave an analysis of everything. It’s important for everyone to be on top of their health. Great service!
Ease of scheduling appointments, clear results
This is my 2nd year using Function Health. I find its a very easy process to get a multitude of blood tests at an exceptional price to keep a check on how my body is doing. I really appreciate the explanation that is provided for each test result once they are analyzed.
Thorough and helpful for my overall wellbeing.
I trust Dr. Hyman and his team to identify the important items to screen. This screen did me a very good service: my blood lead levels were very high this time vs no blood lead level in previous test. So I am acting on it. I could have missed it if I had not done this screening test and could have sustained irreversible damage to my health. The results give me an excellent big picture with details so I know how I am doing. Quest is an excellent and trustworthy lab so I trust the results. I appreciate Dr. Hyman for setting up something I can do to take care of myself without hassling with health insurance with its usual obstacles. The cost is very reasonable considering the number of items that are tested and screened so this is a very good value.
Blood collection, testing, reporting are all perfect. The final report does not factor rest of the data that I have provided - change in medicines, weight change, etc. Further in my case for a trip to Kenya, I took anti-malaria medicine that could have some impact on my urine, etc. The information should be collected and used in an analysis.
3 separate apptointments needed to give blood, instead of 1. ?!?!
Hi Jason, we're sorry to hear this was your experience. This isn't the experience we aim to provide. Our team worked with you directly to explain why multiple lab visits were needed in your case. If you need any further assistance, please reply to our previous email or reach out to us at [email protected]
Everything was fantastic. The follow up data was very impressive. I would and have highly recommend.
Just having all of the days presented clearly and visually, along with the notes finally gives me a good picture of my health. Add-on tests can get expensive, but the basic membership is very worth it. Nice app as well.
Great and informative but results take long
