Novacyt S.A. announced that, further to the announcement on 27 July 2020, the company has launched a CE-Mark approved serology (antibody) 96-well plate ELISA (enzyme-linked immunosorbent assay) test for the detection of IgG antibodies to SARS-CoV-2 derived from plasma and serum samples. The test has been launched by Microgen Bioproducts Limited (Microgen), which is part of Novacyt's protein diagnostics division Lab21. The new antibody test complements Novacyt's existing COVID-19 product portfolio, in particular the Company's polymerase chain reaction (PCR) test for COVID-19, to provide clinicians with the diagnostic tools to detect and differentiate between active and prior SARS-CoV-2 infections in patients. The new antibody test has been validated in a study where 1,673 patient samples (112 positive samples and 1,561 negative samples) were evaluated. The test demonstrated 100% sensitivity in patients that were tested at 14 days after testing positive for COVID-19 by a PCR test. The antibody test also demonstrated 99.4% specificity.
