Question

Quizplus · Accepted Answer

A Mantoux test measures a person's immune response to the bacteria that cause tuberculosis (TB), and the size of the induration (swelling) at the site of injection determines the test result. An induration of 5 mm indicates exposure to TB, but not necessarily active disease, as it can also occur in people who have received the BCG vaccine or who have previously been infected with TB. Option A is incorrect because it implies active TB disease, which cannot be diagnosed by the Mantoux test alone. Option C is also incorrect because it contradicts the result of the test. Option D is not recommended because BCG vaccination after a positive Mantoux test may result in false-positive results on future tests, rendering them less useful for diagnosing TB infection.
