Critical Use of Nucleic Acid Amplification Techniques To Test for Mycobacterium tuberculosis in Respiratory Tract Samples

摘要

The usefulness of employing Belgian selection criteria before performing nucleic acid amplification techniques (NAT) was evaluated. The results of this study show that for smear-negative patients with an abnormal chest radiology result in the absence of a respiratory tract infection by bacterial pathogens, testing with NAT is of major benefit.
