Wonderful in every way. WELL worth the money, plus you can use HSA/FSA funds to cover it (we did). Really thorough testing and thorough details on the results! Extremely useful. Get the baseline info on your health for an inexpensive price. Clear and detailed information on their website, very simple to navigate and simple to go through the process of setting up the tests and getting your results.

Thank you for the kind words. We’re glad to hear you found the process simple, the information valuable, and the results easy to navigate. It’s great to know the insights have been useful for you.

Tried to become a customer. Taking payment was easy. Getting an actual lab appointment or speaking with any customer service person about it, no chance. There’s got to be a better option.

Waste of $365. Looks months to finally get my clinical results which were pathetic. I could have found the same info with Google. They also use AI to generate your clinical results and other plans on their website. Complete waste of money. Just go to Quest and do it yourself.

Excellent service. I am really happy with it. However, Function Health will NOT work with you to substantiate your purchase for FSA purposes. No matter what request I made, their replies sounded like a broken record: They don't do this... They don't do that. So be ready to see your FSA claims denied and just pay directly out of pocket. Hence the three stars. But let me be clear: It's totally worth it.

horrible customer service, like speaking to a chat bot, tone deaf, insensitive, not helpful

Excellent choices and pricing that doesn’t compare to anything out there. I’m able to watch and identify issues. These options and tests are outstanding.

I joined Function Health for proactive testing and it caught my elevated lipase level before any doctors did. That early warning led to a diagnosis of mild pancreatitis, which we’re now managing successfully with diet, Creon, and monitoring. The dashboard is easy to use and the results gave clear, actionable insights. If you want real visibility into your health instead of waiting for symptoms to get bad, Function Health is worth it.
