Predictive value of human placental lactogen determinations in pregnancy.

The relation of human placental lactogen (hPL) levels to pregnancy outcome was studied in normal and preeclamptic pregnancies, hPL determinations were performed between 38 and 44 weeks of gestation, and the results were compared with birthweight and Apgar scores in three groups. The results of hPL determinations permitted prediction of intrauterine growth retardation in all except 2 patients. The value of hPL measurement as a screening test in pregnancy is noted.
