I worked as a Phlebotomist in a very busy outpatient lab. It was not unheard of to draw 4-5 TBgolds per day as we had Rheumatologists, Dermatologists and several Dr's who had studies going on so it was hard to distinguish whether we were drawing for exposure or medication monitoring. I did just get the reults of my CT which was negative. I am concerned about atypical Tb ie: extraaxial musculoskeletal infection.
