Low cycle threshold value in Xpert MTB/RIF assay may herald false detection of tuberculosis and rifampicin resistance: a study of two cases

Tijdschriftbijdrage - Tijdschriftartikel

We report 2 cases for whom Xpert MTB/RIF falsely signaled rifampicin-resistant tuberculosis, based on unusually low cycle threshold and 3 of 5 probes missing. Other mycobacterial tests were negative. Further optimization of the Xpert MTB/RIF algorithm is warranted.
