Improved Sensitivity of Capillary Electrophoresis for Detection of Bisalbuminemia

ESR results obtained with the three ESR methods. The bias between TEST-1 and the manual Westergren method was 2.7 mm/h (agreement limits, 33 to 8 mm/h). Concerning reproducibility, the mean interassay CV was 7.9%. The ESR values for samples stored for up to 24 h were, on average, 4% lower than the initial values. However, after storage for 48 h, ESR values were, on average, 24% lower than the initial values. Therefore, we consider the maximum permissible storage time to be 24 h.
