The clinical performance of the EGV1 self-monitoring blood glucose system.Clin Chim Acta. 2012 Jul 11; 413(13-14):1039-44.CC
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.
