I don't know why you're being down voted, of course you can't test for everything, and you're going to start with the most likely causes.

The frustrating part for me is when people think of the symptom as the cause. Like they understand that multiple things can cause a fever, but they don't understand that multiple things can cause bronchitis.

When I was a kid I had "sinusitis" multiple times a year, but my doctor never explained to me that it could be the same or different causes. When I learned that '-itis' just meant inflammation, it blew my mind. I have done my best to spread that knowledge ever since.
