| Abstract: | The purpose of this prospective study was to determine whether serial maternal venous hPL determinations could identify pregnancies resulting in growth-retarded infants from a selected population at presumed high risk for IUGR. Our results demonstrated that mean hPL levels in IUGR outcome pregnancies were significantly lower than normal after 33 weeks' gestation. Mean hPL was also lower in some pregnancies resulting in normal-weight neonates with abnormally low PI or short CHL, suggesting that these neonates, despite normal birth weight achievement, may represent previously unsuspected. |
