AFB Susc. Pyrazinamide

What is the AFB Susceptibility – Pyrazinamide test?

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


Who needs this test?

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


How is the test conducted?

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


What do the results indicate?

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


Why is this test important?

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