PCR of Gargle Lavage Samples as Effective as Nasopharyngeal Swabs to Identify SARS-CoV-2 Infection
Twenty-six subjects from a cohort of 80 tested positive for SARS-CoV-2 via nasopharyngeal swab, and all 26 tested positive using gargle lavage (mouthwash), according to new research published in Microbiology Spectrum, the new open-access journal of the American Society for Microbiology. That’s good news, because nasopharyngeal swabbing, currently the gold standard for collecting samples for COVID testing, has a low rate of acceptance due to the discomfort of having a nasal passage swabbed .The detection method for testing samples used in this study is the highly sensitive real time polymerase chain reaction (RT-PCR). Our results show that in all cases, where people were positively tested by the gold standard nasal swabbing, one could also detect the virus in gargle lavage by the same RT-PCR method.
