Negative Latex-Fixation Test in Psoriatic Arthritis

open access: closedArchives of Dermatology, 1961
The ability of rheumatoid serum to cause nonspecific agglutination of fine particulate matter was first noted by Cecil in 1930, 1 who studied the effects of rheumatoid sera on certain strains of streptococci. Since that time many tests for rheumatoid arthritis, which are dependent on that phenomenon, have been developed.

Quality Control of the Latex-fixation Test

American Journal of Clinical Pathology, 1979
Standardization of the latex-fixation test for the detection of rheumatoid factor may be achieved by the preparation of a standard reference serum. A number of guidelines for the quality control of precision and sensitivity of the test are suggested.

Clinical Observations on the Latex Fixation Test

Postgraduate Medicine, 1962
The latex fixation test gave positive results in 49 per cent of patients with rheumatoid arthritis. Two groups, composed of 95 patients with positive responses and 97 patients with negative responses, were studied to determine the relationship between the test results and the degree of dilution, duration of the disease, age of the patient, functional ...

The latex fixation test

The American Journal of Medicine, 1956
Abstract 1.1. A latex fixation test for the serologic diagnosis of rheumatoid arthritis is described. 2.2. The principle of the test is similar to that of current technics depending upon the agglutination of erythrocytes but the substitution of biologically inert polyvinyl toluene and polysterene latex particles of uniform size obviates ...

[The latex fixation test using whole serum and an euglobulin fraction in various arthritic disorders].

Arthritis & Rheumatism, 1958
The euglobulin fraction of sera from patients with rheumatoid arthritis gave a higher percentage of positive latex fixation tests than whole sera. The results of such tests correlated with the number of diagnostic criteria for rheumatoid arthritis ...
