From: Validation of an automated assay for measurement of bovine plasma ceruloplasmin
Bland–Altman difference plot for ceruloplasmin levels in bovine plasma samples (n = 40) using an automated and a manual assay. Y-axis: bovine plasma ceruloplasmin (BPCp) obtained with the automated assay minus BPCp value obtained with the manual method (Difference). X-axis: mean of the BPCp values obtained with the two methods. The mean of the differences or bias (line marked as mean) and the 95% limits of agreement (mean ± 1.96 SD) are included in the graph
