Cartridge-based Nucleic Acid Amplification Test (CBNAAT) is used to detect Mycobacteria tuberculosis and rifampicin-resistance using GeneXpert IV Dx system and the Xpert MTB/ RIF cartridge.

The CBNAAT system integrates and automates sample processing, nucleic acid amplification, and detection of Mycobacteria tuberculosis and rifampicin resistance.

The system utilises the use of single-use disposable CBNAAT cartridges that hold the Polymerase Chain Reaction (PCR) reagents and hosts the PCR process.

The process involves the following steps:

In Ziehl-Neelsen microscopy, the carbol fuchsin fuchsin stain is heated to enable the dye to penetrate and bind the waxy mycobacterial cell wall. Following acid-decolourisation, the sputum smear is counterstained with methylene blue which stains the background material, providing a contrast blue colour against which the red AFB can be seen.
