What exactly is the Mantoux Test? | Pulmonologist in Mumbai | Dr. Parthiv Shah

Tuberculosis skin test and PPD test are other names for the Mantoux test. It is used to detect latent or asymptomatic Tuberculosis (TB). Tuberculin, a purified protein derivative (PPD) derived from tuberculosis-causing bacteria, is injected into the patient's forearm and the skin response after 48-72 hours is used to diagnose tuberculosis infection. A chest X-ray is also advised in the event of a positive Mantoux test.

Because a latent TB infection may progress to active infection, rapid detection and treatment are essential. It is preferred over other TB blood tests in the case of children below 5 years. It is also recommended for persons who have had direct contact with TB patients or are immunocompromised.
