Investigation of Anti-SARS-CoV-2 IgG and IgM Antibodies in the Patients with COVID-19 by Three Different ELISA Test Kits

We examined anti-SARS-CoV-2 IgG and IgM antibodies in 45 serum samples from 26 patients with COVID-19, who were admitted in our hospital by using three different ELISA kits. All patients had pneumonia at admission, and 7 patients required mechanical ventilator support and grouped in severe case. Anti-SARS-CoV-2 IgG and IgM antibodies turned to be partially …

Evaluation of Antibody Response in Symptomatic and Asymptomatic COVID-19 Patients and Diagnostic Assessment of New IgM/IgG ELISA Kits

This study aims to study the immune response and evaluate the performances of four new IgM and five IgG enzyme-linked immunosorbent assay (ELISA) kits for detecting anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies against different antigens in symptomatic and asymptomatic coronavirus disease 2019 (COVID-19) patients.

A total of 291 samples collected from symptomatic and asymptomatic RT-PCR-confirmed patients were used to evaluate the ELISA kits’ performance (EDI, AnshLabs, DiaPro, NovaLisa, and Lionex). The sensitivity was measured at three different time-intervals post symptoms onset or positive SARS-CoV-2 RT-PCR test (≤14, 14-30, >30 days). The specificity was investigated using 119 pre-pandemic serum samples. …
