目的-评价FreeStyle Navigator动态血糖监测系统在I型糖尿病儿童中的准确性和精密度。研究设计和方法-在30名I型糖尿病儿童中（平均年龄11.2 ± 4.1岁），将导航仪血糖值与在住院临床研究中心获得的血液样本的参考血清葡萄糖值进行比较，并在中心在实验室中使用己糖激酶酶法，在门诊环境中使用辅理善血糖仪。中位数绝对差（AD）和中位数相对绝对差（RAD）计算传感器-参考和传感器-传感器pairs.RESULTS -中位数AD和RAD分别为17 mg/dl和12%，分别为1,811住院患者传感器-参考对和20 mg/dl和14%，分别为8,639门诊患者对。两次同步导航器测量（n = 1，971）之间的中位RAD为13%，住院患者环境中91%的探头和门诊患者环境中81%的探头具有中位RAD
OBJECTIVE - To evaluate the accuracy and precision of the FreeStyle Navigator continuous glucose monitoring system in children with type I diabetes.RESEARCH DESIGN AND METHODS - in 30 children with type I diabetes (mean age 11.2 +/- 4.1 years), the Navigator glucose values were compared with reference serum glucose values of blood samples obtained in an inpatient clinical research center and measured in a central laboratory using a hexokinase enzymatic method and in an outpatient setting with a FreeStyle meter. Median absolute difference (AD) and median relative absolute difference (RAD) were computed for sensor-reference and sensor-sensor pairs.RESULTS - The median AD and RAD were 17 mg/dl and 12%, respectively, for 1,811 inpatient sensor-reference pairs and 20 mg/dl and 14%, respectively, for 8,639 outpatient pairs. The median RAD between two simultaneous Navigator measurements (n = 1,971) was 13%, Ninety-one percent of sensors in the inpatient setting and 81% of sensors in the outpatient setting had a median RAD
