So streamlined and easy while providing so much more useful data than I have ever received at my general Practitioner office.

We’re delighted to hear the testing process was straightforward and that the insights provided were valuable. We appreciate your thoughtful feedback.
Natasha B.
I enjoy the ease of having all the labs I want to run versus having a doctor tell me they don't think certain labs are necessary or my insurance company denying my request.
Response from Function HealthAug 15, 2026
Thank you for sharing, Natasha. We’re glad Function makes it easy to access the testing that matters to you and stay informed about your health. We appreciate having you with us!

I love Function Health. You get such a comprehensive look into your health with the multitude of lab tests. The results are explained very well. They give recommendations for supplements but do not try to sell you on their own products. They are not selling anything other than recommended tests. A great value for a huge insight into your health. I highly recommend.

I appreciate the service that Function provides. The clinician feedback was excellent. I’ve been with Function for over three years now so I’m able to view my health trends and also see how changes in diet and exercise affect my health data.

I love the thorough explanation of lab markers, their integrative approach, the addition of wearables like Fitbit/iwatch to further keep track of your progress, AI chat for questions with customer personalized answers. Overall, it is the best investment in health and prevention of chronic disease. Thank you for your commitment to customers!

The scheduling and testing are very smooth and easy to do. Results start rolling in within a week and are generally all back to you within 4 weeks. Once the results are all in the clinician notes/summary follows within a day or two.
