The evaluation of an automated mariPOC SARS-CoV-2 antigen test compared to RT-qPCR SARS-CoV-2 assay and comparison of its sensitivity in Delta- and Omicron-variant samples.

ABSTRACT:

Background

The rapid diagnostics tests for SARS-CoV-2 antigen vary in their sensitivities, and moreover, genomic mutations may further affect the performance of the assays. We aimed to evaluate the analytical performance of an automated antigen assay and compare its sensitivity in Delta- and Omicron-variant positive clinical samples.

Material and methods

The analytical performance of an automated mariPOC SARS-CoV-2 antigen test was evaluated on a population of community-dwelling subjects with mild respiratory symptoms or being asymptomatic investigated by the RT-qPCR Allplex™ SARS-CoV-2 assay. The sensitivity and specificity of the antigen test were evaluated on prospective 621 nasopharyngeal swabs along with oropharyngeal swabs. The sensitivity regarding variants determined
