متن کاملFalse-positive tuberculin skin tests: what is the absolute effect of BCG and non-tuberculous mycobacteria?
BACKGROUND Despite certain drawbacks, the tuberculin skin test (TST) remains in widespread use. Important advantages of the TST are its low cost, simplicity and interpretation based on extensive published literature. However, TST specificity is reduced by bacille Calmette-Guérin (BCG) vaccination and exposure to non-tuberculous mycobacteria (NTM). METHODS To estimate TST specificity, we revie...
