Placental protein 12 (PP12): a new test for the prediction of the small-for-gestational-age infant

R J Howell et al. Br J Obstet Gynaecol. 1985 Nov.

Abstract

The circulating levels of placental protein 12 (PP12) and placental lactogen (hPL) were measured in 501 women between 36 and 41 weeks gestation. There was a significant positive association between hPL levels and infant birthweight and a significant negative association in the case of PP12 levels. The clinical efficiency of elevated PP12 levels in the prediction of low-birthweight infant at term compared favourably with that of reduced hPL levels.
