hey, i worked in a medical office where i dropped one of the doctors Burs in the garbage, that garbage had tissues with blood and cotton balls with blood and everything that touched the patients mouth. Its a dental office. It was not the Sharps box. Anyways, this alarmed me, i waited 92 days to test and I tested "non reactive" but this still makes me extremly worried and uneasy. some people say the window period is 6 months.
