AFB SENSITIVITY 1ST LINE DRUGS SIREP BY BACTEC

You should get an AFB sensitivity test for first-line drugs (SIREP) when your TB culture is positive, ideally before or early in treatment, to confirm the medicines will work. It is especially recommended for previously treated TB, relapse, poor treatment response, persistent positive sputum, and contacts of drug-resistant TB patients.

For an AFB sensitivity test for first-line drugs (SIREP), the sample is usually sputum or an existing positive TB culture. If sputum is needed, collect an early morning sample by coughing deeply, after rinsing your mouth with plain water. Avoid toothpaste or mouthwash. Ideally, give it before starting TB medicines, and inform your doctor about past TB treatment.

No, fasting is not required for an AFB sensitivity test for first-line drugs (SIREP). If a sputum sample is collected, it is best given early in the morning before eating or drinking, after rinsing your mouth with plain water. Often, the test uses an existing positive culture, needing no new sample.
