Mantoux test
The Mantoux test also called the Purified Protein Derivative (PPD test) or Tuberculin Sensitivity Test is a diagnostic tool for tuberculosis. The test shows if a person has been exposed to TB bacteria, but it does not indicate if the infection is active or latent or if the patient is currently infectious. This test is an example of a Type IV or cell-mediated/delayed hypersensitivity immune response.
