A new simple identification of rheumatoid factor on nitrocellulose was developed that allows quantitative detection. Verification of the results was done by comparison with the established Waaler-Rose-Test and Latextest: Correlation coefficient of linear regression for Latextest rLR = 0.717 and for Waaler-Rose-Test rLR = 0.665; Spearman rank correlation coefficient for Latextest rs = 0.798 and for Waaler-Rose-Test rs = 0.700. The interday and intraday variations showed good results. The histograms for different patient groups showed significant distributions. The nitrocellulose-test satisfies ARA-criterium No. 6.
开发了一种在硝酸纤维素上对类风湿因子进行新型简单鉴定的方法，该方法可进行定量检测。通过与既定的瓦勒-罗斯试验和乳胶试验比较来验证结果：乳胶试验的线性回归相关系数rLR = 0.717，瓦勒-罗斯试验的rLR = 0.665；乳胶试验的斯皮尔曼等级相关系数rs = 0.798，瓦勒-罗斯试验的rs = 0.700。日间和日内变化显示出良好结果。不同患者组的直方图显示出显著分布。硝酸纤维素试验符合美国风湿病学会标准第6条。
