Function made my lab draws a breeze--easy set up. Labs populated rather quickly. I also found the feedback--dietary considerations and supplement recommendations--rather helpful.

I've been using the function health bloodwork bio markers for a few years now and have gotten others to use it as well. I'm happy the price has been lowered...I think even more people will be encouraged to use this.

Everything about this experience was wonderful. The lab tech was great and painless. Very professional. I was very pleased with that. But the absolute best part was the clinician's explanation about what all the test results meant. It was in simplified English so I could understand everything. I would recommend this to anybody.

My experience with Function Health has been nothing but positive. The app makes it easy to schedule lab visits. It is high touch, meaning you’ll receive reminders of the upcoming appointment and what you need to do to prepare. A couple times my lab had issues and the appointment needed to be rescheduled. Function stepped right in and helped me get rescheduled. Their follow-up is phenomenal. Aside from the ease of the app, once you receive your results, the information is laid out so clearly and the clinician’s notes are comprehensive and very easy to understand. I love the recommended foods and supplements. And when you do your 6-month follow-up lab tests, it’s very cool to compare, see improvements and areas still needing improvement. Having all this information in one place is great. Highly recommend!
