Mantoux test is a sensitive but non-specific in the diagnosis of active tuberculosis. The positive cut-off of 10 mm in a person without BCG and 15 mm with previous BCG is appropriate. The interpretation of Mantoux needs to be correlated to the patient’s clinical context. Mantoux test may have a role in assisting extrapulmonary tuberculosis and latent tuberculosis in children.
