Tuberculin skin testing ________.

Question

Quizplus · Accepted Answer

Tuberculin skin testing (also known as Mantoux test or purified protein derivative (PPD) test) is a procedure in which PPD, a purified protein filtrate prepared from killed Mycobacterium tuberculosis, is injected intradermally. The test is used to detect whether a person has been exposed to TB. A positive result indicates a previous exposure to TB, but it does not necessarily mean that the person has active TB disease. Therefore, choice C is correct, but not choice D, which implies that a positive test result always indicates active TB. Choice B is also correct, as PPD is indeed a purified protein filtrate of M. tuberculosis. Therefore, the correct answer is E (all of the choices are correct).
