Checking in for blood draws at Quest was more complicated/time-consuming than it should have been. Had to repeat some of my lab tests (I'm unsure why that was). The amount of tests for the cost was good; clinician report was fairly helpful.

The review of my labs wasn't very helpful as to what to do next. I'm a physician and I still didn't understand why many supplements were recommended, a ridiculous number in fact. It appeared to be AI generated, very generic. It took weeks to get results. No specifics given to improve my abnormal lab results. This may be helpful for someone who can't get medical care due to lack of insurance and wants some basics done.

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.

The large amount of testing data was very useful and the cost was reasonable.

I thought Quest did a great job with the blood draw, and I really like the app and how the quick results were posted. I was very disappointed with the clinician's notes. It wasn't any different from what was already posted in the app on each of the results explanations. It truly felt like AI wrote the report. It didn't give any additional insight into my current health situation. All the suggestions seemed exactly the same: eat better foods, sleep more, exercise more, and reduce stress. Those are very generic suggestions that I knew before I purchased Function. Also the number and kinds of suggested supplements felt overwhelming.

Just getting all the metrics in one place was a great thing I understand most of them, but I think the explanations as how each metric relates to one another needs more refinement.I just had hoped they would make more “ suggestions,” of what a person could do without seeing an allopathic physician.

Making the appointment was easy but l really Thought the amount of blood drawn was sufficient that is why l haven't been back. I struggled to understand the biomarkers but I am working on improving my health .
