摘要
Background: Mean corpuscular volume (MCV) of stabilized whole blood used for quality control (QC) of hematology analyzers exhibits a tendency to increase during storage. The aim of this study is to evaluate the extent of biases over time with 3 most widely used control materials and to map out a strategy to overcome the data shift of MCV on daily QC.practice. Methods: QC results of TESTPoint tested by ADVIA 2120i, e-CHEK tested by XE 2100, and 6C Cell Control tested by DxH 800 were analyzed. Results: MCV of all control materials showed a tendency to increase over time. By the fifth week, most of the materials showed biases larger than one standard deviation, with some exceeding a bias of four standard deviations. Conclusions: Laboratories should apply appropriate QC strategies in MCV tests by considering their individual quality and efficiency requirements. (C) 2014 Elsevier B.V. All rights reserved.
