They lay it out so it is easily understood. They give diets and supplement information.

Comprehensive data and information on my health. I look forward to an interactive means to ask and receive explanations. When I have questions, the responses are prompt and very helpful.

The notes were somewhat helpful, however no insight given on how much of the supplements to take or how often. Also disappointed with no live person to talk to. The testing was great, but the limited communication wasn't what I thought I was getting with my subscription. Hard to ask questions also.

I liked the broad number of tests, ease of making appointments for labs and generally found dashboard easy to use. However, I would have liked to see which individual tests that were pending on dashboard ( just lets you see tests completed ) and I couldn't figure out how to export report for sending to my MD. While a great tool, if you don't have a family practice MD who knows about this service or knows anything more than very basic lab test results, your left with figuring out best next steps yourself.

I've been going to Naturopathic Doctors since 2010. Each time it's a different lab with paper print outs. In the past few years, I even created a Spreadsheet to track that data from year to year. I discovered Function Health in 2024 and it's been a game changer. All my results in one place and even more data than what the doctors intially order. I feel so much more knowledgeable about my results and can always go back to review. I'm a customer for life!

The reminders prior to the visits along with step by step instructions on how to check-in! I loved having the summary for the results, which made it very easy to read. The ability to also share the results via PDF with my doctors was fantastic!

The information that I received from function health was invaluable. From the blood results spanning a whole wide range of things, to the doctors notes and the advice on what to eat and what to avoid and what supplements to take and what to avoid. I am very grateful. Thank you.
