Haemolytic complement level and ragocyte (R A cell) concentration in synovial fluid.

Abstract
An inverse and statistically significant (P = 0. 05) correlation was demonstrated between the hemolytic complement level and the ragocyte (R A cell) concentration in synovial fluids from patients with a variety of joint disorders. The mean correlations was even more significant (P < 0. 01) in fluids from patients known to suffer from rheumatoid arthritis.
