About this test

The AFB sensitivity test (13 drugs) checks whether Mycobacterium tuberculosis grown in culture is sensitive or resistant to 13 anti-TB medicines. These typically include first-line drugs (isoniazid, rifampicin, ethambutol, pyrazinamide, streptomycin) and second-line drugs such as fluoroquinolones, amikacin, linezolid, ethionamide, clofazimine, and others.

Results identify MDR-TB, pre-XDR TB, and XDR-TB, which need specialized treatment.

It helps doctors design the most effective treatment regimen, avoid ineffective drugs, and prevent treatment failure and further resistance.

Questions about this test

When should I get the AFB sensitivity 13 drugs test?

You should get an AFB sensitivity (13 drugs) test if your TB culture is positive and drug resistance is suspected, such as when TB is not improving despite treatment, sputum stays positive, or TB relapses. It is also recommended for previously treated patients, contacts of MDR-TB cases, and when rapid tests show rifampicin resistance.

How should I prepare for the AFB sensitivity 13 drugs test?

For an AFB sensitivity test, the sample is usually sputum. Collect an early morning sample by coughing deeply, after rinsing your mouth with plain water. Avoid toothpaste, mouthwash, or food beforehand. Ideally, give the sample before starting or changing TB medicines, and inform your doctor about past TB treatment. Results may take several weeks.

Do I require fasting for the AFB sensitivity 13 drugs test?

No, fasting is not required for an AFB sensitivity (13 drugs) test. However, if a sputum sample is used, it is best collected early in the morning before eating or drinking, after rinsing your mouth with plain water. Avoid toothpaste or mouthwash before collection for accurate results.
