Laboratory testing for SARS-CoV-2 virus and the consequent respiratory coronavirus disease 2019 (COVID-19) is categorized into methods that detect the viral presence and methods that detect antibodies produced in the host as a response to infection. Methods that detect viral presence in the host excretions measure current infection by SARS-CoV-2 whereas the detection of human antibodies exploited against SARS-CoV-2 evaluates the past exposure to the virus.


This review provides a comprehensive overview of the use of saliva as a specimen for the detection of SARS-CoV-2, the methods for the salivary diagnostics utilized till very recently, and the arisen considerations for the diagnosis of COVID-19 disease.

The major advantage of using saliva as a specimen for the detection of SARS-CoV-2 is that saliva collection is a non-invasive method that produces no discomfort to the patient and permits the patient's home self-sampling techniques in order to protect health providers from exposure to the pathogen. There is an urgent need to increase the active research for the detection of SARS-CoV-2 in the saliva because the non-invasive salivary diagnostics may provide a reliable and cost-effective method suitable for the fast and early detection of COVID-19 infection.
