Overview of Tuberculosis and TB Skin Test
Tuberculosis (TB) is a potentially fatal contagious disease that can affect almost any part of the body but is mainly an infection of the lungs. It is caused by a bacterial microorganism, the tubercle bacillus or Mycobacterium tuberculosis. Although TB can be treated, cured, and can be prevented if persons at risk take certain drugs, scientists have never come close to wiping it out. Few diseases have caused so much distressing illness for centuries and claimed so many lives.
The tuberculosis skin test is also known as the tuberculin test or PPD test. The standard recommended tuberculin test is the Mantoux test, which is administered by injecting a 0.1 mL volume containing 5 TU (tuberculin units) PPD into the top layers of skin of the forearm. Skin tests should be read 48-72 hours after the injection.
