This image depicts a patient returning for interpretation of a Mantoux tuberculin skin test at 48 hours, demonstrating a 15 mm induration at the injection site. The test is administered by intradermal injection of tuberculin, typically on the volar surface of the forearm. A positive reaction is defined by induration, with or without erythema, indicating prior exposure to Mycobacterium tuberculosis.
