2 days agoIgM is a less specific antibody that is quite a bit stickier than IgG. The stickiness of IgM makes tests that measure IgM less reliable and more likely to be falsely positive. Why do we use IgM assays at all? It is because IgM is produced first. IgM can be found in people very early during infection, well before IgG antibody is produced. results for this questionIs IgG positive?Is IgG positive?IgM is negative, but IgG is positive The patient has recently been infected with COVID-19 and now has protection against COVID-19. 4.
