目的:探讨空腹末梢血与静脉血在2型糖尿病筛查诊断中的偏性,为2型糖尿病筛查诊断提供参考依据。方法:应用末梢血与静脉血检测空腹血糖,判定糖尿病、空腹血糖受损阳性率,并与口服葡萄糖耐量试验检测结果进行比较,观察2种血检测结果偏性。结果:空腹末梢血检测2型糖尿病阳性率5.64%,空腹血糖受损阳性率8.32%,空腹静脉血检测2型糖尿病阳性率3.53%,空腹血糖受损阳性率5.64%,末梢血与静脉血检测空腹血糖一致率87.66%,偏差率12.34%;末梢血与口服葡萄糖耐量试验判断一致率76.26%,偏离率23.74%,静脉血与口服葡萄糖耐量试验判断一致率81.43%、偏离率18.57%。结论:末梢血或静脉血检测结果均不足以作为糖尿病确诊依据。
Objective: To investigate the bias of fasting peripheral blood and venous blood in the screening of type 2 diabetes mellitus, and to provide a reference for the screening of type 2 diabetes mellitus. Methods: The fasting blood glucose was measured by peripheral blood and venous blood to determine the positive rate of diabetes and impaired fasting blood glucose. The results were compared with those of oral glucose tolerance test. The biases of the two blood tests were observed. Results: The positive rate of fasting blood glucose was 5.64%, the positive rate of fasting blood glucose was 8.32%, fasting venous blood was 3.53%, fasting blood glucose was 5.64%, peripheral blood and venous blood The concordance rate of fasting blood glucose was 87.66% and the deviation rate was 12.34%. The consistency rate of peripheral blood glucose and oral glucose tolerance test was 76.26% and the deviation rate was 23.74%. The consistent rate of venous blood and oral glucose tolerance test was 81.43% and the deviation rate was 18.57%. Conclusion: The peripheral blood or venous blood test results are not sufficient as the basis for the diagnosis of diabetes.
