Nasopharyngeal swab

The nasopharyngeal swab has been the gold standard among the various methods of COVID detection since the beginning of the pandemic. With this method, it is especially important that the swab is performed properly, which is why this is only carried out by trained medical professionals. The subsequent analysis of the swab for the virus can be done by means of the PCR procedure or through a rapid antigen test. However, this has an effect on the reliability of the test result.
