A positive TB skin test or TB blood test only tells that a person has been infected with TB bacteria. It does not tell whether the person has latent TB infection (LTBI) or has progressed to TB disease. Other tests are needed to see whether the person has TB disease. The table below is a summary of different diagnostic tests conducting at community level:
