Abstract

A simple, rapid, and sensitive solid-phase immunoassay procedure for the determination of estrone-3-glucuronide (E1-3-G), which uses chemiluminescence as the end point in unextracted morning urine, is described. Thirty-one patients undergoing induction of ovulation in an in vitro fertilization (IVF) unit participated in the study. From day 3 of the menstrual cycle until the day of hCG administration, morning blood samples and morning urine specimens were collected for the determination of serum 17β-estradiol (E2) and urine E1-3-G, respectively. A good correlation was noted between E2 measured by radioimmunoassay (RIA) and the E1-3-G measured by chemiluminescence immunoassay (CIA), from day 5 up to the day of hCG administration (0.6 < r < 0.85, P < 0.001). It is evident from this study that the CIA measurement of E1-3-G in morning urine is an accurate and rapid (2.5 hours) method and is convenient for monitoring induction of ovulation with human menopausal gonadotropins.
