RF-WAALER

Determination of rheumatoid factors
SLIDE TEST

PRINCIPLE

RF-Waaler Test is a rapid slide agglutination procedure, based on a modification of the Rose-Waaler technique developed for the direct detection and semi-quantitation of rheumatoid factors (RF) in serum.

The assay is performed by testing a suspension of stabilized sheep red cells sensitized with rabbit gamma globulin, against the unknown serums. The presence or absence of a visible agglutination,  indicates the presence or absence of RF in the samples tested.
