Sampling site for SARS-CoV-2 RT-PCR-An intrapatient four-site comparison from Tampere, Finland.

Anterior nasal swab performs as good as nasopharynx swab with saliva also finding all the positives but with higher cycle threshold values. Thus, we can conclude that anterior nasal swabs can be used for SARS-CoV-2 detection instead of nasopharyngeal swabs if the situation would require so.
