(ELISA) SARS-CoV-2 IgG-AB (S1) I.S. (ELISA) Phone : +44 (0) 7873 494300 Results Unit Reference Range 0.2 0.4 Ratio Ratio < 0.8 < 0.4 The Abbott chemiluminescent microparticle immunoassay SARS-CoV-2 IgG test is designed to detect IgG antibodies to the nucleocapsid protein of SARS-CoV-2 in serum and plasma from patients that may have been infected by COVID-19. This test has not been Food and Drug Administration (FDA) cleared or approved and has been authorized by FDA under an Emergency Use Authorization (EUA). This test has been authorized only for the detection of IgG antibodies against SARSCov-2, not for any other viruses or pathogens. Current detection of IgA-AB against SARS-COV-2 without simultane- Ous detection of IgG. An isolated IgA result indicates a recent in- fection. Since a false positive result cannot be excluded (specificity approx. 88 %), we recommend direct detection of SARS-COV-2 by PCR from the nasopharyngeal swab and a serological follow-up in 2 weeks to confirm seroconversion.
