Quick, thorough, and flexible. The instructions were helpful as well as the overview and plan for correcting any labs that were off. It gives people control of their health and information ongoing to see changes good or bad and take action to prevent disease.

Thank you for trusting us with your health, Katherine. Every review helps more people discover what’s possible with Function.
Wonderful platform and great value. Only thing I wish was offered would be a 30-45 minute phone consultation to review the test results and develop an action plan.

Improving website however the amount of time it takes after having testing to get results is a bit long. I am sure dealing with others companies is part of that.

Thanks for sharing—feedback like this helps us refine our product so every member feels the full value of their Function experience.
Love the plethora of advanced tests and how easy it is to schedule. Really a great way to bring this previously untouchable health watch toolset to the consumer. My only rec is that it would be better if you could get a more in-depth analysis of results. I can do part of it myself and my GP can help but I really need a functional doctor’s analysis and that’s super expensive outside of the product. Would be nice to get that inside. And yes, I’m aware of the current analysis and your current policy to not diagnose or give deep personal recs.

Clear directions on testing. Quest did their best. The results report was extremely good. I still don’t understand how to address the problem results. . It would be helpful if you directed us to websites that would explain the results.
