title: MicroSed SR-system: new method for determination of ESR--efficacy and expected value.
abstract: This study was undertaken to examine the efficacy of a new erythrocyte sedimentation determination (ESR) method, MicroSed SR-system, and study the expected value of the ESR obtained with this method among the healthy Thai population aged 17 to 50 years old. This was a comparative study between standard Westergren and the MicroSed SR-system for ESR on 100 individual subjects. In addition, the expected range was calculated based on ESRs of 50 males and 50 females. From the study, the comparison-of-methods plot the comparison-of-methods plot MicroSed SR-system (Y) VS Westergren method (X) gave the least square linear regression equation of Y = 0.1.371 X + 0.842 (r = 0.904). The expected range of ESRs for males and females are 0 to 25.6 mm/hr and 0 to 37.5 mm/hr, respectively. Based on study results, the MicroSed SR-system method ESR result correlates well with the standard Westergren method. The derived expected range of ESR was similar to the standard references. The MicroSed SR-system can be used as an alternative method for ESR determination.
