The accuracy of urinary oestriol and serum levels of human placental lactogen (HPL) and heat stable alkaline phosphatase (HSAP) as indicators of feto-placental function was studied in 76 patients with high risk pregnancy. Feto-placental dysfunction was predicted correctly by plasma HPL in 80%, by urinary oestriol in 70%, by serum HSAP in 47%, and by the complementary use of HPL and oestriol in 90% of the cases. Normal fetoplacental function was predicted correctly by plasma HPL in 94%, by urinary oestriol in 96%, by serum HSAP in 80%, and by the complementary use of oestril and HPL in 100% of the patients. The probability of feto-placental dysfunction with a pathological value was 88% with urinary oestriol, 84% with plasma HPL and 100% with the parallel use of oestriol and HPL. A normal value assured undisturbed feto-placental function in 89% with urinary oestriol, in 92% with plasma HPL and in 96% with the parallel use of oestriol and HPL.
