This community is amazing. We never got this depth of health summaries from our doctors. Now we get constant feedback from each lab tests as well as connections to the supplements we need based on our bloodwork markers. Simply health care at its best.

I’m very satisfied with the ease of the process and trust my local Quest office. I was impressed with the clinician notes and AI analysis of the test results.

I now feel so informed and have a plan based on my functional blood test results. It is so empowering to design a dietary plan and exercise plan that aligns with what my body needs. In a time when getting proper medical care seems like an uphill battle… Function helps you understand your results, develop a plan, and preemptively make changes before health problems arrive. If you’re on the fence… make the move.

The allergy version of my blood work was a joke. Very few items in results and the results were absolute opposite of my known food allergies of the last 4 decades and multitudes of previous tests including skin testing and genetic testing. Very disappointed in function on this test.

Thorough labs with great write ip for results. No need to beg Doctor office for certain labs such as ApoB. Im stopping review. I do not trust trustpilot.

STARR G.
Hello! I would like to thank you immensely for your thorough review of my mid year Function blood tests. I so appreciate your promptness in reviewing it. The informative explanation of why each test matters, along with advice on further treatment is extremely helpful in knowing what I need to do to go forward with better health. I had this mid year test later then I wanted to, due to me treating SIBO and leaky gut. I’m so tired of taking so many supplements and it has become too expensive. I believe my heart health, diabetes,and fatty liver have not been addressed, or should I say put on the back burner due to suffering from SIBO for the past year. I’ve backed off from the supplements for the past few weeks as I need a break. Thank you for caring and Function Health is a company I tell others about. Hopefully, I will be able to afford renewing my membership. Blessings, Starr
