title: The current role of daily serum estriol monitoring in the insulin-dependent pregnant diabetic woman.
abstract: This retrospective analysis of the use of serum estriol levels for antenatal assessment was performed in an effort to determine if routine, late third-trimester, daily serum estriol monitoring of insulin-dependent pregnant diabetic women can still be justified. Estriol profiles of 170 diabetic pregnancies, managed under a consistent protocol of weekly contraction stress tests and daily serum estriol assessments, were reviewed. A total of 4612 estriol determinations were performed. Nearly 4% of the estriol determinations showed a 35% fall from the mean of the previous three highest consecutive values. Forty-seven percent of the patients had at least one fall of this magnitude. Eighty-five percent of the fetal heart rate tests performed in association with an estriol fall were normal. A fall in estriol was not found to be associated with a higher risk of having a positive contraction stress test, either at the time the estriol fall was recognized or at any time during the patient's antepartum course. Although use of this strict protocol combining the use of weekly contraction stress tests and daily serum estriol determinations provided a safe method of antepartum assessment, there is little evidence to support the routine use of daily serum estriol monitoring in insulin-dependent pregnant diabetic women.
