A COMPARISON OF THE ROSE-WAALER, LATEX FIXATION, "RA-TEST," AND BENTONITE FLOCCULATION TESTS

A Comparison of the Rose-waaler, Latex Fixation, "ra-test," and Bentonite Flocculation Tests.

The bentonite flocculation test of Bozicevich, Bunim, Freund, and Ward (1958), the latex fixation test of Singer and Plotz (1956), and the "RA-test" (a latex reagent for use as a slide test) of Hyland Laboratories have been compared with each other and with a modified Rose-Waaler test, the behaviour of which has been previously extensively investigated. In these tests sera from 2,250 patients w...

Synovial fluid Waaler-Rose and latex tests.

Positive serum Waaler-Rose and Latex tests provide a useful confirmation of the clinical diagnosis of rheumatoid arthritis, but a significant number of patients remain persistently negative. Positive synovial fluid tests were reported in a few seronegative patients by Rodnan, Eisenbeis, and Creighton (1962), who suggested that this might be useful in diagnosis. We have reviewed all the WaalerRo...

Quantitative aspects of the latex-fixation and Whaaler-Rose tests.

The latex-fixation test (Singer and Plotz, 1956) is widely used as a serological criterion for rheumatoid arthritis (Alexander and McCarthy, 1966; Walton, 1968). The test is often carried out in serial dilution, by which a titre as well as an agglutination pattern is obtained. The usual practice is to choose a borderline titre in an empirical way and to call all titres above the borderline valu...

Detection of rotavirus by Latex Agglutination Test (Rotales); Comparison with Electron Microscopy and Complement Fixation Test

Rose-Waaler test using a rapidly prepared serum fraction.

The use of a serologically active fraction of serum in parallel with whole serum, in testing for the sheep cell agglutinating factor in rheumatoid arthritis, was suggested by Svartz and Schlossmann (1953) and by Ziff, Brown, Badin, and McEwen (1954). Claims of higher sensitivity and specificity have been re-emphasized in more recent publications (Ziff, Brown, Lospalluto, Badin, and McEwen, 1956...
