title: Are 24-hour urine collections necessary for the measurement of steroid excretion rates?
abstract: In the assessment of ovarian activity, testicular response in human chorionic gonadotrophin (HCG), and placental and fetal viability during pregnancy, measurements made on small samples of urine may be used to monitor changes in 24h steroid output; the collection of 24h urine specimens is not necessary. For women, 24h output approximately 10 R (R, steroid/creatinine in small urine samples; concentrations expressed in SI units of amount). For men, 24h output approximately 14 R.
