What saliva testing isPeople may find providing saliva as a sample for COVID-19 testing to be a more comfortable and convenient way compared to a nasopharyngeal or nasal swab taken by a healthcare worker. Saliva samples can be self-collected and dropped off at a collection point or observed by health care worker. Testing is then undertaken by accredited laboratories and follows almost the same process as the testing of samples from nasopharyngeal swabs – both are Reverse Transcription Polymerase Chain Reaction (RT-PCR) tests which identify genetic material in the virus.
Saliva can also be used as a sample for some rapid antigen tests, which is processed differently. There is more information on the Rapid antigen testing page.
