For a PPD test to be positive,induration (swelling with increased firmness)must be present.A diameter of 10-mm induration would be a positive finding in an immigrant from a region with high TB infection.Erythema alone does not indicate a positive finding.A 5-mm induration is not large enough to indicate a positive finding.A small pustule in a homeless client undoubtedly is an infection but may not be due to the PPD test.
