Reference Values Of Genexpert MTB/RIF Resistance (Pulmonary) Test

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 tests depict 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 provide information of the resistance potential to rifampicin.


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.
