ESR 자동측정기기 StaRRsed의 유용성 평가

Abstract

For the estirnation of erythrocyte sedimentation rate(ESR), conventional methods are widely used because they are simple and economical, but have disadvantages of difficulty in standardization and quality control. So we evaluated the clinical usefulness of an automated ESR measurement as comparing with conventional Westergren method. We measured ESR with samples from 117 patients and volunteers. The EDTA blood samples were used for Westergren method and auomated StaRResd method. After drawing the blood the tests were completed in two hours. Westergren method was performed and a 30-min and a 60-min. test were performed for the StaRRsed method and the results were compared. The ESR results of the test for the Westergren, the StaRRsed-30 min and the StaRRsed-60 min. methods were 20.6±21.5 mm/hr, 12.2±15.2 mm/hr and 13.1±14.4 mm/hr, respectively. The correlation coefficients were 0.970(p<0.001), 0.982(p<0.001) and 0.987(p<0.001) StaRRsed-30 min. and StaRRsed-60 min. showed a good relationship with the Westergren method. So, both the StaRRsed-30 min. and -60 min. method can be used instead of the Westergren method. And to reduce the estimated time, the StaRRsed-30 min. method can be used more effectively.
