Depends . . .: Positive mantoux tuberculin skin test (also known as PPD or purified protein derivative) is determined by diameter of induration, not erythema, as well as risk of infection. Chat w/your provider to discuss your next step as well as options. Check out http://www.Cdc.Gov/tb/publications/factsheets/testing/skintesting.Htm.
