[Development of a new quantitative rheumatoid factor test].
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.
