I have mixed feelings about Function…
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!!

Slow, glitchy app, and sometimes misleading.

Function health is by far the best and most extensive blood panel I have done! I am so impressed with the explanation on markers and what drives them up. I also love the lifestyle and supplementation suggestions. I have all of my clients use function! Highly recommend!
