Sampling site for SARS-CoV-2 RT-PCR-An intrapatient four-site comparison from Tampere, Finland.
<h4>Background</h4>SARS-CoV-2 diagnosis relies on the performance of nasopharyngeal swabs. Alternative sample sites have been assessed but the heterogeneity of the studies have made comparing different sites difficult.<h4>Objectives</h4>Our aim was to compare the performance...
