What is the methodology for Labcorp's COVID-19 test?

The Pixel by Labcorp™ COVID-19 at-home kit is a molecular test, also known as a reverse polymerase chain reaction (RT-PCR) test or a nucleic acid amplification test (NAAT).  It is a qualitative assay using PCR technology, which LabCorp played a central role in commercializing when PCR was introduced nearly 30 years ago. The COVID-19 at-home test detects the presence or absence of SARS-CoV-2, the virus that causes COVID-19.
