THE SEDIMENTATION DIFFERENTIAL AGGLUTINATION TEST

Differential agglutination test in rheumatoid arthritis complicated by pneumoconiosis.

During a survey of rheumatoid arthritis in a South Wales mining valley (Miall and others, 1953; Miall, 1955), the differential agglutination test (D.A.T.) was adopted as one of the diagnostic criteria of this syndrome. One of the principal objects of the survey was the further investigation of the observation of Caplan (1953) of an association between an unusual form of progressive massive pulm...

Differential sheep cell agglutination test in rheumatoid arthritis.

In March, 1948, Rose and others described a test for rheumatoid arthritis which depended on the ability of serum from patients with rheumatoid arthritis to agglutinate " sensitized " sheep erythrocytes in much higher titre than normal sheep erythrocytes. The authors reported results in 110 patients, of whom 27 had active rheumatoid arthritis and 16 inactive rheumatoid arthritis, 3 Still's disea...

Mycobacterial agglutination-inhibition test.

The mycobacterial agglutination-inhibition test (MAIT) is described as a modification of the mycobacterial agglutination of Schaefer (MATS). It is an organized assemblage of absorption and agglutination tests which is especially useful in the identification of Mycobacterium avium isolates normally excluded from serological identification because of unstable cell suspension characteristics. The ...

Epidemiology of the sheep cell agglutination test.

Recent research into the nature and significance of rheumatoid serum factors has been largely immunological and biochemical. The epidemiology of these components is virtually unknown. During recent years we have had the opportunity of studying several population samples, and data from these surveys have now been gathered and are presented with particular reference to the epidemiology of the ser...
