1. DNA extraction methods enable molecular detection of Mycobacterium tuberculosis (MTB) from sputum specimens.
2. A sensitive and specific multiplex real-time polymerase chain reaction assay enables simultaneous detection of MTB, isoniazid and rifampin resistance, and Beijing/W genotype.
3. Molecular diagnosis of MTB greatly reduces the turnaround time of conventional culture methods.
