Endoscopic bronchoalveolar lavage to collect samples for microbiological diagnosis

ABSTRACT

The study involved 74 patients (48 males, 26 females, and mean age 61 years). Among these, 54 cases have lower respiratory infection and 23 subjects served as controls. In was found that for selective cases of respiratory infection and have received many antibiotics, 103-4CFU/ml should be considered as positive cutoff. With the positive cutoff of 104CFU/ml, the sensitivity, specificity and predictive value of this technique are 69%, 79% and 69%, respectively.
