tuberculosis test

Any of a number of tests used to detect past exposure to, or current infection by M tuberculosis. See Mantoux test, Tuberculin skin test.
Tuberculosis test
1. Tests that document current infection, either by a direct smear of sputum, or by culturing a specimen, eg sputum, lymph node, lung biopsy; M tuberculosis, is notoriously slow to grow, requiring 3+ weeks for definitive identification when cultured in the traditional fashion; more recently, molecular techniques, eg PCR-have been used to shorten the turnaround time for test results
.
2. Tests that evaluate the immune response, see Mantoux test, Tuberculin test.
Obsolete TTs include colorimetric tests–once believed to measure substance(s) seen in ↑ amounts in Pts with TB, the mirror test and theurorosein test; other TTs, eg the tine and Sterneedle tests, that measure sensitivity to tuberculin, reflect the Pt's immune status, and have been abandoned.
