an intracutaneous tuberculin test using a multiple-puncture, disposable device. It is useful in mass screening of children, but is less accurate than the Mantoux test. Any doubtful reaction to the tine test should be rechecked by a Mantoux test before a follow-up chest x-ray is recommended. The test is read 48 to 72 hours after administration.
application of the skin test to the diagnosis of infection by Mycobacterium tuberculosis in which tuberculin or its "purified" protein derivative serves as an antigen (allergen); injection of graduated doses of tuberculin or of purified protein derivative into the skin, most often by means of a needle and syringe (Mantoux test) or by means of tines (tine test); test material may also be applied by means of a "patch" in which it is absorbed but this method (patch test) is considered less reliable; the test is read on the basis of induration and erythema, the former being considered the more diagnostic of infection with the tubercle bacillus (M. tuberculosis); the test does not distinguish between infection in a resistant person without disease and a person with clinical manifestations of disease.
Etymology: ME, tind, rake tooth; L, testum, crucible
a tuberculin skin test in which a small disposable disk with multiple tines bearing tuberculin antigen is used to puncture the skin. The method is widely used to test for sensitivity to the tuberculin antigen. Induration around the puncture site indicates previous exposure or active disease, requiring further testing. See also tuberculin test.
tu·ber·cu·lin test(tū-bĕr'kyū-lin test)
A dermatologic procedure in which tuberculin or its purified protein derivative (PPD) is injected into the skin; the test is read on the basis of local induration occurring in 48-72 hours.
