Is the precision of currently available glucose meters adequate for gestational diabetes screening?
We performed a prospective cohort study of 62 gravid women and compared the precision of three glucose meters to laboratory standard technology.
The HemoCue coefficient of variation was sufficiently low in venous whole blood and plasma and capillary whole blood and plasma (3.0%, 1.8%, 2.8%, and 2.3%, respectively) to allow use in gestational diabetes screening. The OneTouch II coefficient of variation was sufficiently low in capillary whole blood (2.7%) to allow use in gestational diabetes screening but was too high in venous whole blood and plasma and in capillary plasma (3.6%, 7.8%, and 5.7%). The ExacTech coefficient of variation was too high in venous or capillary whole blood (5.4% and 8.1%) for use in gestational diabetes screening and does not analyze plasma samples.
The HemoCue meter in venous and capillary whole blood and plasma and the OneTouch II meter in capillary whole blood have coefficients of variation low enough for gestational diabetes screening.
目前可用的血糖仪精度是否足以用于妊娠期糖尿病筛查？
我们对62名孕妇进行了一项前瞻性队列研究，并将三种血糖仪的精度与实验室标准技术进行了比较。
HemoCue血糖仪在静脉全血、血浆以及毛细血管全血和血浆中的变异系数足够低（分别为3.0%、1.8%、2.8%和2.3%），可用于妊娠期糖尿病筛查。OneTouch II血糖仪在毛细血管全血中的变异系数足够低（2.7%），可用于妊娠期糖尿病筛查，但在静脉全血、血浆以及毛细血管血浆中的变异系数过高（分别为3.6%、7.8%和5.7%）。ExacTech血糖仪在静脉或毛细血管全血中的变异系数过高（分别为5.4%和8.1%），不适合用于妊娠期糖尿病筛查，且不能分析血浆样本。
HemoCue血糖仪在静脉和毛细血管全血及血浆中，以及OneTouch II血糖仪在毛细血管全血中的变异系数低至足以用于妊娠期糖尿病筛查。
