You schedule your lab draw and that is it. They have a comprehensive interpretation of all the labs and what to work on.

Sadly I’m not impressed with the Customer Service side here. It’s antiquated and you wait for an entire day to have a response from a real person. It took me a week to get a celiac panel add on test scheduled with this process. The other area that’s not good is the add on test process. I could not figure out on my phone app how to schedule the test. I could purchase it easily. But not schedule it. This could just be a problem on the phone app but this should be able to work. The Function Health itself I’m A fan of. Love the tests and the dr overview and the helpful feedback. Biological age is a cool thing to see too. Please work on the other aspects Of this and it’ll be great!

We're glad to hear you're enjoying the testing experience, clinician notes, and biological age feature.

I got my results, though it is not clear wether or not they are complete or if I need to revisit the lab. The website does not work as advertised. I cannot download PDFs to share with my MD. There is a chat bot, but no human support is available. That is just not acceptable service. I would not buy from Function again.

Very sad because I really look up to Dr. Hyman. Overall it was good but the fact that they messed up part of blood test and then gave me a referral $100 credit but said I couldn’t use it on my current membership made no sense. I should be able to use it towards my current membership. Won’t be using this again. Update: They offered me a $50 gift card on a new membership because of my experience 😆 so I have to pay for another membership to use the gift card. That’s even worse than the $100 referral bonus. What a joke.

Joshua
Glad to know there's a simple way to get medical tests done to manage my health even on a short notice and at an affordable cost. I was able to get my first labs done the morning after I signed up and had some results the next day!
Response from Function HealthAug 8, 2026
Appreciate you sharing this, Joshua. We’re glad you were able to access testing quickly and start receiving results soon after. It’s great to hear you’ve found the experience both simple and valuable.

I just can't believe, with today's medical prices, that we could get so many quality lab tests at such a low price. And not only that, but to have a clinician read those results and give clear and helpful advice. Plus the AI assistant for necessary supplements, exercises, meal plans... This is such an amazing service and is valuable whether or not you are insured.
Response from Function HealthAug 8, 2026
Thank you for the kind words, Jeremy. We’re glad you’re finding so much value in the breadth of testing, clear Clinician Notes, and additional insights available through Function. We really appreciate you sharing your experience!
Leah
Very easy process and you get so much information. I learned things about myself and my health that no doctor has ever told me. I got my results, have made changes in my diet and added some supplements. I can’t wait to see what my results will be in 6 months. This experience has been more of a motivator to improve my health than any doctor visit I have ever had. This was also so much cheaper than going through my insurance. I am one happy customer and highly recommend Function Health.
