Measurement of the Erythrocyte Sedimentation Rate by Automated Ves-Matic 20
Keywords:
Automation, Erythrocyte sedimentation rateAbstract
Abstract: The erythrocyte sedimentation rate (ESR) is a simple and inexpensive laboratory test. It is commonly used in clinical practice as an infammatory indicator, particularly in screening and monitonng of many diseases. Because of the bichazard risk of blood contammination inherent in using open-ended tubes by Westergren method, it is now recommended that, a closed system be used in routine practice. The Ves-Matic 20 is one of the automated closed system for ESR which can give results in 25 minutes. In this study, the ESR was determined in 106 hematologically normal subjects (55 males, 51 females), aged 30+11 years, and 103 patients with abnormal ESR. The automated ESR system was compared with standard Westergren and modified Westergren method. Reference values showed similar range but the mean of overall values were statistically significant different. Significant high correlations were found between Ves-Matic 20 and standard Westergren or Ves-Matic 20 and moditied Westergren with the same r = 0:973 (p < 0001) The Ves-Matic 20 is easy to use, it reduces working time, requires little maintenance, and minimal contact with potential biohazard. It could be used as the alternative method to conventional Westergren for the ESR determination.
