I was feeling sick this year so I got tested. Both the rapid and the more accurate lab test that takes 2 days. Both came out negative. In my opinion( and just mine) if you get sick get tested. I go to work everyday and I would not want to come it and get other people sick. So for me getting a result before going back was SOP. Actually before I went back to my regular mtb with friends I waited for the results. It's the kind of a courtesy that should be extended.
