Short review on Saliva PCR Tests

Saliva PCR testing diagnostic accuracy is similar to nasopharyngeal swab testing


Meta-analyses of SARS-CoV-2 RNA detection with different specimen types have shown that sensitivity and specificity of saliva PCR tests are similar to nasopharyngeal swab tests and no significant difference was found (Nasiri K, Dimitrova A, 2021; Butler-Laporte G et al., 2021). Accordingly, the use of saliva specimen is preferable as no close contact to heathcare personnel is necessary (Nasiri K, Dimitrova A, 2021). Another benefit of saliva PCR test is that it is more appropriate for testing of children and quarantined individuals (Butler-Laporte G et al., 2021).
