Abstract
.beta.-2-Microglobulin concentration was determined by radioimmunoassay in the synovial fluid of 12 patients with rheumatoid arthritis and in 10 with other arthropathies. White cell count, total protein concentration, total hemolytic activity of complement and acid phosphatase activity were determined. Only .beta.-2-microglobulin was significantly higher in rheumatoids compared to non-rheumatoid cases. The other parameters showed no significant differences between the 2 groups of patients. .beta.-2-Microglobulin concentration measurement in synovial fluid may be of diagnostic value.
