Table 2 Results obtained from samples of the round robin test. Reference values were obtained from the trial coordinators by a multiplex assay analyzed on a capillary sequencer and reported to our laboratory. Afterwards, the samples were re-analyzed on the QiaXcel Advanced system. All samples could be fully confirmed by analyzing the peak patterns
