Please help me with my positive tuberculosis skin test how lon does it take to heal?

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.
