Abstract

Nineteen patient blood samples each with modified hematocrit concentrations of approximately 20, 30, 40, 50, and 60%, were assayed for their glucose concentration by the Glucometer II. Blood removal from the test strip was by the one- and two-blot techniques. The reference method was the Yellow Springs Instruments (YSI) blood glucose analyzer. Glucometer II results were falsely high for the single blot (13-59%, mean 33%) and double blot (12-41%, mean 19%) at 20% hematocrit and falsely low at 60% hematocrit for the single blot (22-44%, mean 37%) and the double blot (26-49%, mean 43%). At 40-50% hematocrit, Glucometer II and YSI results agreed only for the one-blot technique.

摘要

使用血糖仪II对19份患者血样进行葡萄糖浓度检测，每份血样的血细胞比容浓度分别约为20%、30%、40%、50%和60%。通过单印迹和双印迹技术从试纸上去除血液。参考方法是黄春泉仪器公司（YSI）的血糖仪。在血细胞比容为20%时，血糖仪II的单印迹结果（13%-59%，平均33%）和双印迹结果（12%-41%，平均19%）出现错误偏高，而在血细胞比容为60%时，单印迹结果（22%-44%，平均37%）和双印迹结果（26%-49%，平均43%）出现错误偏低。在血细胞比容为40%-50%时，血糖仪II和YSI的结果仅在单印迹技术下一致。
