TB skin test: The reaction from PPD (tb test) can last for several weeks. Did you get a chest x-ray and placed on anti-tb medicine?

Depends on reaction: The reaction can be just induration which goes down in few days.But if the positive reaction is with break in the skin I have only seen once after doing thousands.Severe reaction may take 2to4 weeks to heal
