Determination of rheumatoid factors
RF-Latex Test is a rapid agglutination procedure, based on modification of the Singer method1, developed for the direct detection and the semi-quantitation on a slide of rheumatoid factors
(RF) in serum.
The assay is performed by testing a suspension of latex particles coated with human gamma globulin against unknown serums. The presence or absence of a visible agglutination, indicates the presence or absence of RF in the samples tested.
