The objective was to compare Zenit RA chemiluminescent immunoassay (CLIA) from Menarini Diagnostics and ELISA from INOVA Diagnostics for the presence of specific anti-Ro/SS-A, anti-La/SS-B, anti-U1snRNP, anti-Sm, anti-Scl-70, anti-Jo-1 antibodies. Results/methodology: We studied 501 samples (178 connective autoimmune disease, 150 other autoimmune or inflammatory disease and 173 other disease or healthy). All samples were analyzed using CLIA and ELISA. The Kappa agreement was excellent for anti-SSA/Ro (0.864), good for anti-SSB/La (0.735), anti-Scl-70 (0.685) and ENA-screening (0.778), moderate for anti-RNP (0.563) and bad for anti-Sm (0.266) and anti-Jo-1 (0.243). Different combination of cut-off improved the specificity and agreement.
Zenit RA CLIA for detecting autoantibodies, provides a simple, useful and accurate tool.
比较美纳里尼诊断公司的泽尼特类风湿关节炎化学发光免疫分析法（CLIA）和英诺华诊断公司的酶联免疫吸附测定法（ELISA）检测特异性抗Ro/SS - A、抗La/SS - B、抗U1snRNP、抗Sm、抗Scl - 70、抗Jo - 1抗体的情况。结果/方法：我们研究了501份样本（178份结缔组织自身免疫性疾病样本、150份其他自身免疫性或炎性疾病样本以及173份其他疾病或健康样本）。所有样本均采用CLIA和ELISA进行分析。抗SSA/Ro的kappa一致性极佳（0.864），抗SSB/La（0.735）、抗Scl - 70（0.685）和可提取核抗原筛查（0.778）的一致性良好，抗RNP（0.563）的一致性中等，抗Sm（0.266）和抗Jo - 1（0.243）的一致性较差。不同的临界值组合提高了特异性和一致性。
用于检测自身抗体的泽尼特类风湿关节炎CLIA提供了一种简单、有用且准确的工具。
