I like the simplicity and clarity in explanation of the results. Easy site navigation. Friendly and accommodating staff when I needed to resolve issue with scheduling

Thank you for sharing this, Inga. We’re glad the results were clear and the experience was easy to navigate, and that our team could help with scheduling.

Getting all that information was invaluable. I’m so grateful this was an option. Seeing a naturopath or functional doc isn’t an option for everyone to get these labs done and western medicine providers could/would NEVER. This is the most amazing starting place.

I appreciate the data provided after the appointments to collect the samples. The biggest problem I have with this organization is that the customer service is absolutely abysmal!! Three attempts to get a blood draw (with the right tubes) for the GRAIL cancer test failed to occur. From what I can tell, the lab (Quest) and Function are not on the same sheet. Quest thinks the customer brings the tubes and Function thinks Quest has the tubes. The ‘customer’ ends up in the middle with no viable solution to a fairly simple issue. Three trips of wasted time and effort for nothing. I’m not trying again!

Thank you for sharing your experience. We’re glad you found value in the data, and we’re sorry for the repeated issues with your lab visits—that’s not the experience we aim to provide. We understand how frustrating this is, especially when coordination falls short. Your feedback helps us improve and better support our members through every step.

I appreciate function health for giving me the tools to be proactive about my health journey without having to go through the traditional medical system. It is easy and convenient to use and the detailed information on real up to date medical advice without the concern of who is profiting from a test, procedure or prescription. Great value for the money!

I have had a great experience with Function. The app is easy to use. Setting up the lab appointment was super simple. I just wish there was a location closer to me. It's very frustrating when going to PCP to get baseline labs ordered. They address the symptoms only then push pharmaceuticals which is disheartening. The report from the lab results is very helpful and I appreciate the recommended foods/supplements. Thank You!
