OBJECTIVE
To evaluate the accuracy of continuous glucose monitoring system (CGMS) during oral glucose tolerance test (OGTT) in the detection of blood glucose changes in glucose stress condition.
METHODS
Forty-nine out-patients with fasting plasma glucose of 3.9-11.0 mmol/L underwent continuous blood glucose monitoring using CGMS for 3 days, and OGTT was conducted on the third day. The venous blood glucose was measured at 0, 30, 60, 90, and 120 min after oral glucose intake, and the accuracy of CGMS during OGTT was evaluated.
RESULTS
The correlation indices between CGMS values and the venous blood glucose values during the entire OGTT and in phases of stable, rapidly rising and falling glucose levels were 0.928, 0.901, 0.924 and 0.902, respectively (P<0.001). Clarke error-grid analysis showed that more than 95% of the measured results fell into the A and B zones.
CONCLUSION
CGMS values show good consistency with venous blood glucose values measured during OGTT. CGMS is accurate in detection of rapidly changing blood glucose during OGTT.
目的
评估连续血糖监测系统（CGMS）在口服葡萄糖耐量试验（OGTT）期间检测葡萄糖应激状态下血糖变化的准确性。
方法
49例空腹血糖为3.9 - 11.0 mmol/L的门诊患者使用CGMS进行连续血糖监测3天，并在第3天进行OGTT。口服葡萄糖后0、30、60、90和120分钟测量静脉血糖，并评估OGTT期间CGMS的准确性。
结果
整个OGTT期间以及血糖水平稳定、快速上升和下降阶段，CGMS值与静脉血糖值的相关指数分别为0.928、0.901、0.924和0.902（P<0.001）。Clarke误差网格分析显示，超过95%的测量结果落在A区和B区。
结论
CGMS值与OGTT期间测量的静脉血糖值具有良好的一致性。CGMS在检测OGTT期间快速变化的血糖方面准确。
