The relationship between amniotic creatinine and maternal serum heat stable alkaline phosphatase

ABSTRACT

Paired estimations of maternal serum heat stable alkaline phosphatase and amniotic fluid creatine concentrations were studied in 83 uncomplicated pregnancies and in 32 mothers with pre-eclampsia. A significant linear relationship between these two biochemical indices was obtained in normal pregnancy but not in pre-eclampsia. There was a good correlation between liquor creatine concentration and birth-weight but not between serum heat stable alkaline phosphatase and birth-weight. (AU)
