Book excerpt: The Technical Advisory Group (TAG) on diagnostics and laboratory strengthening reviewed evidence for the comparability of results of the assays Xpert MTB/RIF and Xpert MTB/RIF Ultra performed on the GeneXpert 6-colour system compared to the 10-colour instrument. The evidence showed that the two systems are comparable in detecting Mycobacterium tuberculosis complex as well as detecting resistance to rifampicin. Based on the conclusion drawn by the TAG, WHO/GTB issues this policy statement in order to guide countries regarding running the two tests on the two systems.
