At the beginning of the pandemic, the only test available was a PCR test, which with an accuracy rate of 63 to 98 percent is still considered the "gold standard" of COVID testing. There are no FDA-authorized, at-home antibody tests. The tests identify people who may need treatment. In early 2020, CDC developed its first laboratory test kit for use in testing patient specimens for SARS-CoV-2. The BD SARS-CoV-2 Reagents for BD MAX™ System is a real-time RT-PCR test intended for the qualitative detection of nucleic acid from the SARS-CoV-2 in nasal, nasopharyngeal, and oropharyngeal swab samples from individuals suspected of COVID-19 by their healthcare provider.
