Ok, I make a check in your Health Monitor and get the result that my breath contains certain values or percentages or whatever of acetone, ammonia, ethan, etc. When I go with these results to my physician does he know what these test results mean? Or generally speaking, are medics normally familiar with the biomarkers in breathed air?
I think a good doctor should know this, just like he knows blood biomarkers.
But to confirm the diagnosis, he will have to conduct additional studies
