What is "mantoux test"

Mantoux test \Mantoux test\ prop. n. (Med.) A skin test for hypersensitivity to tuberculin. It determines whether there is or has been any infection with tubercle bacilli.

The Mantoux test or Mendel-Mantoux test (also known as the Mantoux screening test, tuberculin sensitivity test, Pirquet test, or PPD test for purified protein derivative) is a screening tool for tuberculosis (TB). It is one of the major tuberculin skin tests used around the world, largely replacing multiple-puncture tests such as the tine test. The Heaf test was used until 2005 in the UK, when it was replaced by the Mantoux test. It is endorsed by the American Thoracic Society and Centers for Disease Control and Prevention. It was also used in the USSR and is now prevalent in most of the former Soviet states.
