ABSTRACT
Objective To evaluate the clinical performance of chemiluminescent immunoassay (CLIA) on anti-nuclear antibody(ANA) specific autoantibodies testing.Methods A multi-center clinical study A total of 811 Sera samples were collected from 6 collaborating hospitals during the period of April to July 2016, and tested with CLIA and line immunoassay (LIA) in parallel for autoantibodies to ribonucleoprotein(RNP), smith antigen(Sm), SSA/Ro60,SSB/La, centromere protein B(CENPB), double-stranded DNA(dsDNA), nucleosome(Nuc), and ribosome P protein(Rib-P).The positive rate,specificity and qualitative coincidence rate for each antibody between CLIA and LIA methods were analyzed.All discrepant samples for systemic lupus erythematosus (SLE) highly specific autoantibodies (including anti-Sm, dsDNA, Nuc and Rib-P) were retested by enzyme linked immunosorbent assay (ELISA) and further analyzed with SLE disease cohort using McNemar test.Results The positive rate and specificity of CLIA and LIA for antibodies to ANA specific antigens were comparable.Excellent qualitative coincidence were found between CLIA and LIA for the detection of anti-RNP, SSA/Ro60, SSB/La and CENPB (Kappa>0.75), while the coincidence rate foranti-Sm, dsDNA, Nuc and Rib-P detection were moderate (0.4
