The radioimmunoassay of placental protein 5 and circulating levels in maternal blood in the third trimester of normal pregnancy.

A radioimmunoassay has been developed for placental protein 5 (PP5), a product of the human placenta. Circulating concentrations of PP5 were measured in the third trimester of normal pregnancy in 400 women. Concentrations of PP5 showed a skewed distribution and rose progressively to reach a plateau in the last four weeks of pregnancy. The development of this assay will permit studies on the potential clinical application of maternal PP5 levels during normal and abnormal pregnancy.

Is measurement of placental function and maternal weight worth while?

A prospective survey of 1029 women delivered during 1976 at St. Bartholomew's Hospital was undertaken to assess the predictive value of a variety of clinical, ultrasonic, and biochemical variables in the detection of high-risk pregnancies. The best antenatal predictors of fetal risk were severe pre-eclampsia, depressed maternal serum levels of human placental lactogen, low maternal weight at 32 weeks' gestation, and heavy smoking by the mother. 62% of the high-fetal risk group had one or more of these features, but so did 33% of the controls.
