Subsequent to reviewing 626 perinatal deaths in relation to estrogen assay, 1500 consecutive pregnancies were analyzed in detail in regard to utilization of urinary estrogen assays. 2710 assays were performed on 456 cases. The perinatal mortality rate in this high-risk group was 8.8 per 1000 compared with the overall hospital rate of 15.1. Estrogen assays give efficient aid to pregnancy management economically; ways in which their contribution could be improved are suggested.
