Vicki F.
I appreciated all the information at the end once everything was gathered. It was very helpful. One issue is that I had an order from my doctor for cortisol test the same blood draw time and the Function report was different from the test my doctor ordered. Very interesting. 🤔

Looking over the results, I'm grateful for Function Health. Scheduling is a little glitchy but I was able to get it worked out after some trial an error. The lab messed up with my samples so I had to go back again to get the results. I'm glad that I picked up on the missing information because I think it was unusual. As soon as I reached out to Function, they were on it.
