Validation of self-collected buccal swab and saliva as a diagnostic tool for COVID-19	2020-10-05		.txt	text/plain	4332	311	62	Collection of nasopharyngeal swab (NPS) by healthcare workers (HCW) is currently used to diagnose SARS-CoV-2, which increases the risk of transmission to HCWs. Self-administered saliva and buccal swabs are convenient, painless and safe alternative sample collection methods. In order to validate the use of buccal swabs and saliva specimen as alternative diagnostic tests for SARS-CoV-2, our group performed a cross-sectional study of NPS, self-collected buccal swabs and saliva specimens collected concurrently in order to determine the positive percent agreement (PPA), negative percent agreement (NPA), overall agreement (OA), positive and negative predictive values. In this study, we have shown that saliva tests and buccal swabs were comparable to each other and were in moderate agreement with NPS for the detection of SARS-CoV-2, with PPA between 56 and 66% and PPV 95 to 100%.	./cache/cord-291655-l7mg5a0z.txt	./txt/cord-291655-l7mg5a0z.txt
