Collection Summary: | The study comprises a single urine sample for each participant (n = 99) that was collected at a prenatal visit after ultrasound confirmed a gestation < 20 weeks. Ultrasound imaging was performed by trained sonologists in compliance with standard-of-care. All study sites employed a uniform method of GA assessment, urine collection and handling. Urine samples were aliquoted and frozen at -80°C within 2 hours. Deidentified urine aliquots were shipped on dry ice from each biorepository to Stanford University as a single batch and under continuous temperature monitoring. Urine samples from 20 healthy pregnancies collected between 8 and 19 weeks of gestation at the Lucile Packard Children’s Hospital at Stanford University, served as the validation cohort. |
