Interpreting Mantoux Test results


Interpretations

  • The result of this test is interpreted in terms of induration (palpable, raised, hardened area) across the forearm in millimeters. If there is no induration, the result should be recorded as "0 mm" and it means that you have not been exposed to TB bacilli. 
  • Induration of 5 mm, 10 mm, and 15 mm is considered positive depending on the individual's risk factors. A positive test result indicates TB exposure.
