The zeta sedimentation ratio (ZSR) and activity of disease in rheumatoid arthritis. 1977

M W Morris, and R S Pinals, and D A Nelson

Zeta sedimentation ratios (ZSR) and modified Westergren erythrocyte sedimentation rates (ESR) were compared with an independent clinical assessment of disease activity in 100 patients with rheumatoid arthritis. The correlation between ZSR and ESR was good. Both methods correlated well with disease activity. The ZSR was more frequently elevated than the ESR in each category of disease activity, but the differences were slight. In addition to its practical advantages, the ZSR appears to be a satisfactory method for monitoring the activity of rheumatoid arthritis.
