الإجابة: B. Induration ≥10 mm
Only induration (not redness) is measured, 48-72 h after injection. Healthcare workers (employees in hospitals) fall in the high-risk-setting group where ≥10 mm is positive. ≥5 mm is for HIV, transplant, close contacts and immunosuppressed patients; ≥15 mm is for people with no risk factors.

A reaction counts as positive only above a size cut-off of induration (5, 10 or 15 mm depending on risk), not any visible reaction.
