COVID-19 / Coronavirus Outbreak: Performing a Nasal Swab Test on Patients inside a Rapidly Deployable Facility Optimized for Epidemics

JoVE 6426

While different types of diagnostic tests may be used to detect coronavirus disease, a nasopharyngeal swab test is the most common. The test must be performed by a trained healthcare provider. If cell culture is collected in a wrong manner, the diagnosis obtained may be incorrect.

The World Health Organization (WHO) recommends that providers use a sterile dacron or rayon swab with a flexible, plastic shaft for deep nasal sampling. Cotton, calcium alginate swabs, or swabs with wooden sticks may contain such compounds that can inactivate some viruses and inhibit the diagnostic polymerase chain reaction (PCR). The following protocol describes the proper procedure for collecting a nasopharyngeal swab sample.
