Introduction The Xpert MTB/RIF assay is an automated, cartridge-based molecular test used to detect Mycobacterium tuberculosis (MTB) and rifampicin (RIF) resistance, the most potent first-line anti-TB drug. Endorsed by the WHO in 2010, the Xpert MTB/RIF assay revolutionized TB diagnosis by providing results in less than two …
Introduction Xpert MTB/RIF Ultra is an automated diagnostic test designed for the rapid and simultaneous detection of Mycobacterium tuberculosis (MTB) and resistance to rifampin (RIF). It is a second-generation assay developed by Cepheid to provide significantly higher sensitivity than the original Xpert MTB/RIF, particularly for …
Introduction The Line Probe Assay (LPA) is a rapid molecular diagnostic test used to detect Mycobacterium tuberculosis complex (MTBC) and its resistance to anti-tuberculosis drugs. It identifies specific mutations in the genes associated with drug resistance by hybridizing amplified DNA onto membrane strips. The LPA is a …
