Abstract
The performance of a newly proposed fully automated cassette-based sample-to-results solution for norovirus (NoV) detection, InGenius Norovirus ELITe MGB®, was evaluated. A total of 120 selected archival stool samples from children hospitalized for acute gastroenteritis were used to compare the results to a reference real-time RT-PCR. The InGenius NoV assay showed optimal diagnostic accuracy (sensitivity, 100%; specificity, 95.7%) and was able to correctly detect the entire wide panel of epidemiologically relevant genotypes tested. These preliminary results suggest that the InGenius NoV assay can be recommended as a valuable method for accurate diagnosis of NoV GII infection in epidemic and sporadic gastroenteritis.
