Saliva-based PCR COVID-19 Test
Premier Diagnostics uses a saliva-based PCR test to detect the COVID-19 virus. To take this test, patients excrete saliva into a sterile test tube provided to them at the testing site. The saliva samples are then collected and transported to a processing lab located in South Jordan, Utah. There, the samples undergo a DNA amplification process called Polymerase chain reaction, or PCR. This process amplifies the possibly infected DNA to allow detection of the COVID-19 virus.
PCR tests are 98.9% accurate and have EUA approval from the FDA.
