An alternative Covid-19 RT-PCR Test that uses saliva samples instead of nose swab samples was made available today in Philippine Red Cross (PRC) labs. Valparaiso lab offers saliva COVID-19 test instead of nasal swab. Key Points. Also called a molecular test, this COVID-19 test detects genetic material of the virus using a lab technique called polymerase chain reaction (PCR). The lab then ran 30 nasal swabs that had tested positive for COVID-19 through their novel testing platform. The PRC started offering on January 25, 2021, its Saliva Test after receiving the approval of the Department of Health (DOH). 1 This recommendation comes with several caveats. The COVID nasal swab test, also known as the nasal swab test, is a medical test used to detect viruses in the nose that may cause respiratory infections.

The accuracy of at-home COVID-19 tests can also depend on the type of specimen required, whether a nasal specimen, saliva specimen, or oral swab. A positive antigen test also means you have an active infection, but this assay looks for protein specific to the virus instead of genetic material.
