Objective: assess five EIA tests aimed to quantify specific antibodies to SARS-CoV-2 and compared to a surrogate viral neutralization for assessing neutralizing antibodies. Methods: We conducted a cross-sectional study during the period from July to October 2020, in which the sera of 96 participants whose ages were between 18 and 65 years were evaluated, all recovered from COVID-19 and obtained between 28 and 212 days after the onset of symptoms. ELISA tests used for testing include measurement of total antibodies (IgG & IgM); IgG antibodies against S protein (IgG S1/S2, IgG S, IgG S-RBD); IgG antibodies against nucleocapsid antigens, and IgM antibodies against S-RBD antigen. Pearson's linear correlation coefficient was used to know the degree of correlation between the values of the viral neutralization antibody titer and the values of the titer level of antibodies evaluated by each of ...
