Intrauterine Fetal Growth Retardation: A Comparison of Human Placental Lactogen Urinary Oestriol and Biparietal Diameter Measurements

Abstract
Forty-two ‘at risk’ pregnancies were serially monitored by sonar biparietal cephalometry, 24 h urinary oestriol assays and determination of serum human placental lactogen. The results were assessed by a scoring system, and it was found that a combination of sonar cephalometry and 24 h urinary oestriol assays gave the most reliable prediction of intrauterine growth retardation.
