The novel technique of blood volume detection can improve the reliability and accuracy of a self-monitoring blood glucose system. Self-management of diabetes can be improved, and the glycemic range can be efficiently controlled.
A total of 153 patients with diabetes mellitus participated in the clinical study. The accuracy, blood volume detection, interference, and altitude effect of the EGV1 self-monitoring blood glucose system were evaluated and compared among the fingerstick, alternative site testing, and venous blood.
The EGV1 self-monitoring blood glucose system with fingertip demonstrated an excellent correlation with venous blood (linear regression analysis: slope=1.01, intercept=-0.8972 mg/dl, r(2)=0.96), and with other brands of glucose systems (linear regression analysis: slope=0.99, intercept=+3.5632 mg/dl, r(2)=0.94). The Clarke error grid analysis indicated that the results of fingertip and alternative sites were in the acceptable zones, A and B. The system required 0.6 ul of a blood sample to obtain an accurate reading, and was unaffected by several interferents and altitude.
The EGV1 self-monitoring blood glucose system using various blood samples demonstrated acceptable accuracy and reliability compared to the laboratory reference and other self-monitoring blood glucose systems.
新型血量检测技术可提高自我监测血糖系统的可靠性和准确性。有助于改善糖尿病的自我管理，高效控制血糖范围。
共有 153 例糖尿病患者参与了这项临床研究。评估并比较了 EGV1 自我监测血糖系统在指血、替代部位检测和静脉血中的准确性、血量检测、干扰和海拔效应。
指尖的 EGV1 自我监测血糖系统与静脉血（线性回归分析：斜率=1.01，截距=-0.8972mg/dl，r(2)=0.96）和其他品牌的血糖仪（线性回归分析：斜率=0.99，截距=+3.5632mg/dl，r(2)=0.94）具有极好的相关性。Clarke 误差网格分析表明，指尖和替代部位的结果处于可接受区域 A 和 B。该系统仅需 0.6ul 的血样即可获得准确读数，并且不受多种干扰物和海拔的影响。
与实验室参考和其他自我监测血糖系统相比，使用各种血样的 EGV1 自我监测血糖系统具有可接受的准确性和可靠性。
