The tuberculin skin test (TST), also known as the Mantoux test, is used to determine if a child has been exposed to the bacteria that cause tuberculosis (TB). A small amount of purified protein derivative (PPD) is injected intradermally, and the injection site is examined 48 to 72 hours later for induration (swelling). A positive result indicates exposure to TB but does not confirm active disease; further evaluation is necessary. It's important to consider the child's risk factors and history when interpreting the results.
