Increased sensitivity of sputum microscopy with sodium hypochlorite concentration technique: A practical experience at RNTCP center

摘要

Background:In revised national tuberculosis control program (RNTCP), microscopic examination of sputum for AFB plays an important role in the initial diagnosis of tuberculosis. Bacillary concentration after decontamination and liquefaction by 5% sodium hypochlorite is useful in providing increased sensitivity and safety for handling of specimen.
