The ESR is one of the oldest laboratory test still in use. Although it lacks specificity in diagnosis, it can be effective for monitoring disease activity and following-up. The Westergren method is used for reference method, however coefficient of variation has been described 0.8% to 22.9% according to the literature. Since the ESR was invented in 1921, measurement technique has developed and automated measurement is introduced. We analyzed one hundred forty-three patient samples using SEDIsystem' automated ESR measuring system and compared with modified Westergren and Wintrobe methods. Comparison between SEDIsystem' and modified Westergren for ESR measurement yields the following regression equation; y = 0.863x - 1.69 (r=0.830), SEDIsystem'M and Wintrobe y'= 1.14x - 14.7 (r=0.789), rcspectively. We repeated measurement to evaluate reliability, results are not significant in statistically. In conclusion, SEDIsysten' automated ESR measurement correlated with modified Westergren and Wintro" ; methods, reveal reliable results after 4 hours and can report rapidly for large samples. Thus, these results indicate that SEDIsystenT"' automated ESR measurement may be useful tool for clinical practice.

Abstract PDF: Serum C-reactive protein (CRP) levels and erythrocyte sedimentation rates (ESR) were measured in 46 patients treated with uncomplicated primary hip replacements, 39 total tip replacements and 7 bipolar hip replacements. In uncomplicated primary hip replacements, ESR levels were slightly elevated preoperatively and were variable postoperatively. But CRP was normal before surgery and elevated in postoperative course, but back to normal within three weeks in most cases. Early success of hip arthroplasty is in indicated by normalization of CRP within three weeks, regardless of ESR. Since ESR seems to react somewhat differently from the CRP, both methods are useful in the monitoring of complications after hip arthroplasty.
