GeneXpert MTB/RIF Resistance measures the amount of Rifampicin in your blood.
To reveal the presence of TB bacteria and evaluate resistance to the TB drug, Rifampicin.
Your doctor may recommend this test for you if you show symptoms of MDR TB or HIV Infected TB. The symptoms include:
- Coughing Continuously
- Blood in cough
- Chest pain
- Night sweats
- Sudden weight loss
The test is a molecular test which detects the DNA of Tuberculosis (TB) bacteria.
Reference Values Of GeneXpert MTB/RIF Resistance (Extra pulmonary)
Given the high sensitivity of Xpert MTB/RIF in detecting TB (88%), the negative predictive value (NPV) is greater than 98% irrespective of the prevalence of the disease in that setting.
The test displays the genetic make-up of the bacteria and identifies it this diagnosing the TB infection. If it’s identified, the analysis of the genome will give information of the resistance potential to rifampicin.
Interpretations
For pulmonary specimens, the sensitivity and specificity of the MTB/RIF test were 82.3% and 100%, respectively. The sensitivity of the MTB/RIF assay according to the culture result was 100% (4/4) for smear-positive extra pulmonary specimens and 63% (17/27) for smear-negative extra pulmonary specimens.
