      Hey Potatoman.

      Looking at a scab is very important to understanding how your body heals. If your body did not form scabs, every time you got a small cut, you would need to go to the hospital. Some people do not form scabs properly, so they do have to go to the hospital if they do something like scrape their knee. By looking at someone’s blood or scab, we can tell what sort of scabs they can form.
