Описание
Daily first morning urine specimens were collected throughout the first 8-9 weeks of 151 clinical pregnancies. These specimens are now approximately 20 years in storage, and the stability of markers of placental and corpus luteum function are not known. We will collect new urine specimens for 20 pregnancies to serve as a reference to evaluate the quality of those stored samples.
