Thank you for sharing this. Way to take ownership of your health!
Delay and problems with the appointment due to a parking issues that was not plan in advance even if the person knew exactly where the meeting was taking place. Don’t have the full results because it’s missing blood or something happen with the blood that was collected. I’m from Canada and now I have to spend more money and plan a trip back to the USA to give more blood a second time if I want to get the full results. In conclusion I’m very happy with the experience. Thanks, Jean

Thank you for your feedback, Jean. We understand the frustration this caused and have shared your feedback with our team.
I didn't get my results until you asked me to refer a friend and I told you I didn't have the results back yet. I got a lot of data but not a clear undertanding on how to make sense of it. Also, I fasted for 36 hours before the test, I didn't realize that would skewar the results. As a type 1 diabetic, my results were different than most people's but it didn't feel like that was taken into account in my overall age score. Honestly I feel like I wasted a bunch of money.

Thank you for sharing this! Honored to help you own your health.
It’s awesome to be able to gather that type of information as I ease into age 59 with a Biological Age of 47.5! Even knowing what “Biological Age” means came from Funtion Health!!! Simply being able to identify health problems BEFORE they become real problems is crucial as we grow older! Let’s face it - we aren’t getting any younger, but Function Health can help us live longer! 😉

Appreciate you sharing this. We’re glad the insights have been meaningful. To 100 healthy years.
I would say function really shines with the app and with the customer service. I had to use customer service a couple times and it was fast, kind and easy. The tests and app are great.
