Noma
The cost / value is really great. This same bundle of labs would cost so much more from my PCP. I like the ability to chose what I need to know. There is still some work to be done translating this information for my specific questions. I would really like to have better information about diet, exercise and other health actions directly based on my results. I would also like a longevity focus to the analysis.
