Detect a raised, thickened local area of skin reaction, referred to as induration. Induration is the key item to detect, not redness or bruising. Read skin tests 48-72 hours after the injection when the size of the induration is maximal. Measure the induration - not erythema. Measure and report results in millimeters of induration. If more than 72 hours has elapsed and there is not an easily palpable positive reaction, repeat the test on the other arm and read at 48 to 72 hours after the second administration.
