What does the COVID-19 Rapid POC CE-IVD Test detect? The test detects the presence of patient-generated antibodies against spike protein, the virus which causes the disease COVID-19. The test can detect two types of antibody isotypes: IgG and IgM. IgM antibodies are the first antibodies to appear in response to a novel antigen. They imply a more recently initiated infection. IgG antibodies have a higher affinity for the target antigen, meaning they are more specifically able to bind the substance which caused the immune response. IgG antibodies are generated later in the course of infection. IgM and IgG antibodies can both be present in a sample. This implies that the conversion fr …
