When should the test be performed?
BACTEC MGIT 960 PZA is a qualitative method for assessing the susceptibility of Mycobacterium tuberculosis to pyrazinamide (PZA), one of the key first-line anti-tuberculosis drugs. Indications for performing the test include:
- Confirmed tuberculosis infection
- Monitoring the effectiveness of anti-TB therapy
- Diagnosis of multidrug-resistant tuberculosis (MDR-TB)
- Verifying PZA susceptibility in cases of resistance to other first-line drugs
- Epidemiological studies on M. tuberculosis drug resistance
Test description
The test uses the BACTEC MGIT 960 system to rapidly and accurately assess the growth of mycobacteria in the presence of a critical concentration of pyrazinamide.
- The method is based on detecting M. tuberculosis growth in MGIT (Mycobacteria Growth Indicator Tube) liquid medium under acidic pH conditions
- The system automatically records results and analyzes drug susceptibility
- It provides accurate results in a shorter time compared to classical phenotypic methods
- Automated growth detection eliminates subjective interpretation, increasing the reliability of the test
