Abstract:
Analyses of C3 split products with C3d specificity (C3dg) were performed in 157 synovial fluids (SF) of 129 patients with various known joint diseases. Considerable overlap between all inflammatory infectious, and crystal induced disease categories confines the value of such measurements as a diagnostic guide to only a few clinical situations. In seronegative as well as in seropositive rheumatoid arthritis no correlation between SF C3d levels and erythrocyte sedimentation rate could be found.
