COVID19N-REAAD™ is intended for professional use in detecting COVID-19 patients by detecting patient’s anti-SARS-CoV-2 antibodies. IgG antibodies to SARS-CoV-2 are generally detectable in blood several days after initial infection, although the duration of antibodies is present post-infection is not well characterized. Individuals may have detectable virus present for several weeks following seroconversion.
