During the COVID-19 pandemic, numerous swab samples have been taken for SARS-CoV-2 reverse transcriptase–polymerase chain reaction (RT-PCR) testing. It's called a "PCR assay," which stands for "polymerase chain reaction," and it is a specific type of nucleic acid test. Foamtec Nasopharyngeal Diagnostic Swab. . The PCR test looks for the presence of the COVID-19 virus by detecting its genetic material (RNA) through a technique called reverse transcriptase-polymerase chain reaction (RT-PCR).
