Since most sore throats are caused by viral infections rather than by bacteria, a correct diagnosis is important to prevent unnecessary use of antibiotics. So I was looking at my test results and it seems that the times I feel the worst are when my normal upper respiratory flora levels are reported to be "heavy growth" (HEAVY GROWTH NORMAL UPPER RESPIRATORY FLORA ISOLATED).
