What an interesting article. The last time I was sick my doctor kept throwing around the term "leukocytes count" and I had no idea what he was talking about! I might have had more of a clue had I known leukocytes were white blood cells.
My doctor ordering a leukocyte count makes so much more sense now that I know white blood cells fight illnesses. So it stands to reason if you are ill you will have more white blood cells.
