The concentration of human placental lactogen (HPL), in serum was measured in venous and capillary blood from 31 pregnant women. 14 women had uncomplicated pregnancies. The others had complications including preeclampsia, intrauterine growth retardation, and severe edema. The correlation between values of HPL in venous and capillary blood was high. In all cases the clinical information obtained on placental function was the same, whether HPL was measured in venous or capillary blood. The day-to-day variability was of the same order for capillary as for venous samples. It is concluded that capillary blood may well be used for measurement of HPL in pregnant women. Capillary blood could replace venous blood for measurement of HPL in the supervision of pregnancies complicated by preeclampsia or intrauterine growth retardation.
对31名孕妇静脉血和毛细血管血中的人胎盘催乳素（HPL）浓度进行了测定。14名女性妊娠过程正常。其他女性则有包括先兆子痫、胎儿宫内生长受限和严重水肿在内的并发症。静脉血和毛细血管血中HPL值之间的相关性很高。在所有病例中，无论HPL是在静脉血还是毛细血管血中测量，所获得的胎盘功能临床信息都是相同的。毛细血管样本的每日变异性与静脉样本处于同一水平。得出的结论是，毛细血管血完全可用于测定孕妇的HPL。在监测并发先兆子痫或胎儿宫内生长受限的妊娠时，毛细血管血可替代静脉血用于HPL的测定。
