BACKGROUND: At present, the only reliable test for COVID-19 diagnosis is RT-qPCR. Serological assays have been widely used to increase the detection sensitivity of infected population. Hereby, we report the performance of a new pan-IgG multiplex Enzyme Immunoassay (immunodot) method for exploration of discrepant SARS-COV-2 serological results. METHODS: A retrospective study on 38 residual serum samples from recovered COVID-19 subjects with discordant serological results on Roche and Snibe platforms, were reanalyzed on a new semi-automated pan-IgG immunodot Enzyme Immunoassay, namely COVIDOT-TEST, in order to find the source of discrepancies and to evaluate the latter method. All samples were analyzed on the BlueDiver(R) Instrument and all strips were read by the BlueScan(R) Scanner using Dr DOT(R) Software. RESULTS: Based on our data, subject samples showed specific IgG reactions on >/= 2 different antigens on immunodot strips. Of these 38 samples, 97.4 % of samples showed specific IgG reaction against S1 + S2 antigens, 89.5 % showed against RBD antigen, 86.8 % against S2 antigen reaction on the COVIDOT-TEST kit. Specific IgG-S1 antigen and IgG-N antigen reactions were detected in 73.7 % and 65.8 % of the samples, respectively. CONCLUSION: The new semi-automated pan-IgG immunodot Enzyme Immunoassay method appeared to be a reliable assay to confirm suspicious COVID-19 serological screening results.
