Ratio of human placental lactogenic hormone (hPL) in amniotic fluid/maternal serum
The predictive value of the ratio of hPL concentrations in amniotic fluid/maternal serum has been investigated in 24 complicated pregnancies. A correct prediction of the fetal outcome with respect to low birth weight and/or dysmaturity was found in 75 per cent of the pregnancies compared to 67 per cent for total estriol in serum. Serum hPL alone did not seem to have a satisfactory predictive value in this small study.
