GeneXpert MTB/RIF assay is a rapid diagnosis test of Tuberculosis (TB) and drug resistance. It is revolutionizing TB control with aids in prompt diagnosis and treatment (selection of appropriate TB regimen).
GeneXpert MTB/RIF assay is anucleic acid amplification (NAA) testwhich simultaneouslydetects DNA of Mycobacterium tuberculosis complex (MTBC) and resistance to rifampin (RIF) (i.e. mutation of the rpoB gene)in less than 2 hours. In comparison, standard cultures can take 2 to 6 weeks for MTBC to grow and conventional drug resistance tests can add 3 more weeks.
This system integrates and automates sample processing, nucleic acid amplification, and detection of the target sequences.
