Abstract
The majority of opinion indicates that one of the best means of assessing the fetoplacental unit is by measuring the 24 hour maternal urinary estriol output. The practical disadvantages of such tests are mainly the inconvenience and inaccuracies of 24 hour urine collections. This paper describes our efforts to eliminate this problem. In a series of patients, the estriol/creatinine ( E C) ratio of early morning, single voided specimens were compared with the E C ratios of simultaneously collected 24 hour samples. The correlation was found to be satisfactory enough to make this a useful and reliable means of assessing and following high-risk pregnancies in certain circumstances.
