To determine the precision and agreement of the hemoglobin (Hb) measurements in capillary and venous blood samples by the HemoCue and an automated counter. Hb was determined by both equipments in blood samples of 29 pregnant women. The HemoCue showed low repeatability of Hb measurements in duplicate in capillary (CR=0.53 g/dL, CV=13.6%) and venous blood (CR=0.53 g/dL, CV=13.6%). Hb measurements in capillary blood were higher than those in venous blood (12.4 and 11.7 g/dL, respectively; p<0.05). There was high agreement between Hb in capillary blood by the HemoCue and in venous blood by the counter (r icc=0.86; p<0.01), and also between the diagnosis of anemia by both equipments (k=0.81; p<0.01). The HemoCue seems to be more appropriate for capillary blood and require training of the measurers.
通过HemoCue和自动血细胞计数器来确定毛细血管血样和静脉血样中血红蛋白（Hb）测量的精密度和一致性。对29名孕妇的血样使用两种设备测定Hb。HemoCue显示，在毛细血管血样（CR = 0.53 g/dL，CV = 13.6%）和静脉血样（CR = 0.53 g/dL，CV = 13.6%）中重复测定Hb的重复性较低。毛细血管血中的Hb测量值高于静脉血中的测量值（分别为12.4和11.7 g/dL；p<0.05）。HemoCue测定的毛细血管血中的Hb与计数器测定的静脉血中的Hb之间具有高度一致性（组内相关系数r icc = 0.86；p<0.01），两种设备对贫血的诊断之间也具有高度一致性（kappa值k = 0.81；p<0.01）。HemoCue似乎更适用于毛细血管血，并且需要对测量人员进行培训。
