tuberculin
TB screening substance
Tuberculin is a protein extract derived from the bacterium that causes tuberculosis, used in diagnostic skin tests.
A small amount injected under the skin produces a reaction in people who have been exposed to TB: The nurse measured the tuberculin test site after 48 hours.
The test indicates exposure, not necessarily active disease.
