Tamara
Very helpful - all of the feedback from the physician. I was getting anxious seeing results come in so I stopped looking until the doctor reviewed. Felt much better after that. Staff at the lab were very friendly. The only thing I’m missing is recommendations for supplements or lifestyle changes to improve numbers. I guess I have to take this info to my primary to get that, but would have been nice to receive tips from the Function physician.

I had an excellent experience with Function Health. From start to finish, their customer service was outstanding. The staff was responsive, professional, and very understanding, making the entire process easy and stress-free. I was very impressed with the detailed health insights I received. The comprehensive testing gave me a much clearer understanding of my overall health and identified areas I can focus on to improve my long-term well-being. The results were easy to understand and provided valuable information that I can discuss with my healthcare provider. If you’re looking for a proactive approach to your health with exceptional customer service and meaningful, in-depth health information, I highly recommend Function Health.
