Two vs. three sputum samples for microscopic detection of tuberculosis in a high HIV prevalence population
Noeske J et al. - In this population with a high prevalence of human immunodeficiency virus (HIV) with late case presentation, smear microscopy of two morning specimens detected at least as many positive cases as the classical strategy, and no cases were lost before treatment.
