A standard dose of 5 Tuberculin units (0.1 mL)is injected intradermally (into the skin) and read 48 to 72 hours later. A person who has been exposed to the bacteria is expected to mount an immune response in the skin containing the bacterial proteins.

The reaction is read by measuring the diameter of induration (palpable raised hardened area) across the forearm (perpendicular to the long axis) in millimeters. No induration should be recorded as "0 mm". Erythema (redness) should not be measured.

If a person has had a history of a positive tuberculin skin test, another skin test is not needed.
