What is GeneXpert test?

I recently came across the latest technology in pathology called geneXpert test which is helpful in detecting TB. What exactly is this test and how does it test the disease in a person?

It is a nucleic acid (DNA) amplification test to detect TB from a sputum specimen. It also tests for resistance to Rifampicin, an antibiotic used to treat TB.
