Study design. PMAT's ROC curves for anti-dsDNA, anti-SmD1 and anti-RibP autoantibodies were obtained with samples from healthy controls, AID no SLE and SLE patients. CIA's data proceed exclusively from SLE patients. Then, with samples from patients with SLE, an agreement between both techniques was performed, and additional data was correlated with antibody titers obtained from both technologies. Abbreviations: AID: autoimmune disease; SLE: systemic lupus erythematosus; PMAT: particle-based multi-analyte technology; CIA: chemiluminescence assay; SLEDAI; SLE Disease Activity Index 2000.
