Antiphospholipase A2 Receptor Autoantibodies: A Comparison of Three Different Immunoassays for the Diagnosis of Idiopathic Membranous Nephropathy

Figure 3

Comparative analysis (IMN versus controls). ALBIA and the CBA-IFA were compared to the diagnosis of the subjects tested. (a) With an area under the curve (AUC) of 0.78 (95% CI: 0.74–0.82) for CBA-IFA and of 0.84 (95% CI: 0.78–0.89) for ALBIA, both assays showed similar discrimination between IMN and controls. Cut-off values are indicated by the arrows. (b) Comparative descriptive analysis shows the prevalence of anti-PLA2R antibodies in different cohorts measured by ALBIA.
