摘要：
The Cobas Amplicor PCR system (CA-PCR) was compared with culture and staining for acid-fast bacilli (AFB) for the early detection of Mycobacterium tuberculosis in respiratory clinical specimens and otherwise normal sterile body fluids. The sensitivity, specificity and positive and negative predictive values of CA-PCR were determined with AFB-positive and AFB-negative specimens. The sensitivity of CA-PCR ranged from 73.6% to 100% for AFB-positive samples, while sputa collected after bronchoscopy were the most useful specimens, with 70% sensitivity and 98.6% specificity among the AFB-negative samples.
