Hi, I am a senior year BSN student. I am from India. I don't how old I was but I had a BCG vaccine when I was little. until now, I always had negative PPD test. Last week I had my TB test and came back positive. I have already scheduled my chest Xray. but now I am little concern. Last two PPD test I had from health department and for this one, I went to little clinic @ kroger. The lady who read my TB test, she told me you always test positive after your BCG vaccine. Now I am confused. Do I still have to do two step TB test?
