title: Evaluation of an automated direct fluorometric method for determination of total estrogens in pregnancy urine.
abstract: The value of urinary estriol as a measure of placental function has been previously established. The authors have modified to total automation a previously published method. The method operates at an analytical rate of 30 samples per hour. Results are expressed as mg. estrogen/gm. creatinine (E/C). In normal pregnancy values rise from a mean of 18 at 31 weeks gestation of 43 at term.
