Circulating immune complexes (IC) were detected and quantified in serum of patients with rheumatoid arthritis (RA) by three methods: radiolabeled Clq binding test, anticomplementary activity and optical density of 3% PEG precipitated sera. Rheumatoid factor (RF) is characterized in PEG precipitates by the Waaler-Rose reaction. The relationship between IC, complement and RF levels are analyzed.
