The Diesse Mini-Ves (DMV) erythrocyte sedimentation rate (ESR) analyzer was designed to improve efficiency in determining the ESR. We compared the Westergren ESR method with the 4-sample DMV ESR analyzer for performance and clinical correlation. This prospective observational study, conducted at a 450-bed tertiary medical center, evaluated 291 paired samples from subjects with various systemic inflammatory conditions. Linear regression analysis revealed a statistically significant correlation between the 2 methods. Satisfactory precision of the DMV analyzer was obtained for high and mid-range ESR values. The 4-sample DMV ESR analyzer was precise and comparable in results to the Westergren ESR method. This DMV ESR analyzer is now used at our medical center based on quality control improvements that include a faster, safer, and more standardized ESR method. Hospital or office-based clinical laboratories should consider using the 4-sample DMV ESR analyzer in place of the Westergren method.
