Excellent blood tests with content. Lots of recommendations for healthier living. However a lot of redundant summary feedback which was obviously written with AI. A better experience would be a with live consultation. Just my 2 cents.

This test far exceeded the standard lab tests done by my primary care physician. I gained the information I needed to make changes to my diet and lifestyle to experience abundant health.

too slow to provide numerical results. Took 2 weeks. I usually see my lab result numbers within 24-48 hours

I had my blood drawn at the quest lab on Thursday. On Saturday evening some results came in that were very alarming. I called my Dr the following morning and she told me I needed to go into the ER immediately. Turns out the blood draw was wrong and now I get to pay for a visit to the ER because everything else was closed and I couldn’t reach anyone at function health to help. They didn’t even alert me that my results warranted a visit to the hospital. I did this test because I’m anxious about my health and this had me spiraling.

I feel like I don’t quite know what to do with my results. It would be nice to meet with a professional after
