Quizplus · Accepted Answer

A 2 mm area of erythema is considered a negative result for the Mantoux test. Typically, a positive result is defined as an area of erythema greater than or equal to 5 mm in certain populations (such as those who are immunocompromised) or greater than or equal to 10 mm in the general population. Therefore, a result of 2 mm would not typically indicate a need for further testing or intervention.
