Saliva As a Diagnostic Tool in Covid 19 Detection, A Review

Background and Aim: Delayed detection of SARS-CoV-2 has been a major hindrance in curbing the current COVID-19 pandemic. Wide spread testing is the most practical way out of the current crisis. The current gold standard for COVID-19 diagnosis is real-time reverse transcription polymerase chain reaction (RT-PCR) detection of SARS-CoV-2 from nasopharyngeal swabs. However, collecting nasopharyngea...
