It is difficult to distinguish between symptoms caused by infection of the HCoV-NL63 virus and those caused by other common human viruses, making diagnosis and detection complex. Reverse transcription polymerase chain reaction of samples collected through nasopharyngeal swab is the most commonly used method for detection of the virus. Viral culture or blood serum testing for antibodies may also be used for the confirmation of infection.
