The effect of changes in packed cell volume was studied in two commonly used reagent strip methods (Dextrostix and Reflotest) of measuring blood glucose and in a filter paper blood spot method. It was found that the results with both the reagent strip methods were greatly haematocrit-dependent. Attention is drawn to the possibility of false diagnoses of hypoglycaemia in haemoconcentrated patients and of normoglycaemia in anaemic patients.
研究了红细胞压积变化对两种常用的测量血糖的试剂条法(Dextrostix和Reflotest)以及滤纸血斑法的影响。结果发现,两种试剂条法的结果都极大地依赖于血细胞比容。需要注意的是,在血液浓缩的患者中可能会出现低血糖的误诊,而在贫血患者中可能会出现血糖正常的误诊。
