The detection of blood glucose level of finger capillary blood and vein blood by using three kinds of glucose meters and automatic biochemistry analyzer and the linear regression analysis between every glucose meter and automatic biochemistry analyzer / 中国医学装备

ABSTRACT

Objective:To compare the results of three kinds of glucometers and automatic biochemistry analyzer for the detection of blood glucose level of finger capillary and vein blood, and adopt linear regression to analyze their relationship.Methods: 204 patients with or without diabetes were enrolled in this study. Their finger capillary and vein blood were detected by three kinds of glucose meters and automatic biochemistry analyzer, respectively. And these data were analyzed by using linear regression and pair-t-test.Results: The comparative results revealed that the order of correlation between every glucose meters with automatic biochemistry analyzer was Accuchek higher than GT-1920 and GT-1920 higher than One Touch when the range of hematocrit (Hct) value was in 35.1%-51.6%. The correlation of Hct between every glucose meter and automatic biochemistry analyzer when the range of Hct was 25.0%-35.0% was significant higher than that when the range was 35.1%-51.6% (t=2.19,P<0.05). For finger capillary blood, the bias of One Touch was largest, while for vein blood, the bias of GT-1920 and One Touch were better. Besides, the detected results of blood glucose both of GT-1920 and One Touch were significantly higher than automatic biochemistry analyzer(t=2.34,P<0.05).Conclusion: There were better correlation between every glucose meter and automatic biochemistry analyzer, respectively, and the correlations between them can be effected by Hct. While there were still certainly difference between them.
