Correlation of homemade ELISAs with external validated serological tests. Spearman correlation was used to determine the association between (a) anti-RBD titer obtained by RBD ELISA and anti-RBD IgG concentration tested by validated UMELISA SARS-CoV-2 ANTI-RBD test and between (b) half-maximal neutralization dilution (NT50) obtained by conventional virus neutralization test (cVNT) and half-maximal inhibitory dilution (ID50) detected by surrogate virus neutralization test (sVNT). A significant correlation was observed (p < 0.0001).
