Results came in quickly. Summary followed almost immediately and was extremely helpful. I love the ability to generate protocols. Will definitely renew for year 3.

Barb G.
It is easy informative and it allows for personal adaptations to optimize health. The only criticism I have is all the added test options which are unclear if they would really benefit me. It adds a lot of costs chosing them.

Barb, we’re glad you’ve found Function easy and informative. We also hear your feedback about wanting more clarity around which additional testing options may be relevant to you. We appreciate your perspective and will keep it in mind as we continue improving the member experience.
Kim
Comprehensive testing and clinical notes! Function Health made lab testing easy. Results were easy to interpret. Clinical notes were comprehensive. I had a little difficulty downloading information on my phone. I expect that had more to do with the user than the interface. ;-) All-in-all, I had a terrific experience!

Christina
The process of booking and modifying appointments for bloodwork is so simple and quick. The bloodwork itself is an easy procedure handled well by partner Quest Diagnostics. The Function app makes it easy to go through all the test results, see which are good or bad and improving, and gives a thorough explanation. The clinician notes really shine once you have had bloodwork annual testing twice, because then there are trends for the clinician to analyze.

It was easy to set up the appointment. The wait time at the facility was minimal. Within a couple of days the results started coming in. The explanations of each test are very understandable . The process was simple . I like how they separated the results by color and concerns.i find the website very navigable.

Joseph D.
With limited testing, my doctors somehow stumbled into the correct diagnosis. Based on these results, I'm now content with my present health care. I wish I had this complete picture 10 years ago! I think I could have avoided a lot of hassle of the journey and had a better quality of life along my life journey.
