AFB Susc. Pyrazinamide

This test determines whether Mycobacterium tuberculosis (TB bacteria) is resistant to pyrazinamide, a key anti-TB drug.

Patients diagnosed with tuberculosis, especially those not responding to standard treatment, may need drug susceptibility testing to guide therapy.

A sputum or tissue sample is cultured, and the bacteria are exposed to pyrazinamide to check for resistance.

If the bacteria are resistant, alternative medications must be used to prevent treatment failure and drug-resistant TB.

Drug-resistant TB is a major public health concern. This test helps tailor effective treatment regimens, reducing transmission and improving recovery rates.
