Accuracy of the Ansh anti-SARS-CoV2 IgG and IgM ELISA. A, B. Deming regression (A) and Bland-Altman (B) analysis between Ansh Labs (reference laboratory) values and Ansh ELISA on the Dynex DS2 in our laboratory. Mean bias of the Dynex-DS2 relative to the manufacturer’s method was 3.9 AU/ml. C, D. Deming regression (C) and Bland-Altman (D) analysis between Ansh Laboratories values and the Ansh SARS-CoV2 measured on Dynex DS2 in our laboratory. Mean bias of the Dynex-DS2 relative to the manufacturer’s method was −0.7 AU/ml.
