%X Lily K Pemberton, Irina Burd, Eileen WangDivision of Maternal Fetal Medicine, Department of Obstetrics and Gynecology, University of Pennsylvania, Philadelphia, PA, USAAbstract: We evaluate the current available literature on first trimester measurement references, how critically these data have been evaluated in subsequent studies, and the generalizability of the standards across different populations. We will then discuss the significance of first trimester dating for genetic screening tests and how growth in the first trimester may predict later pregnancy outcomes, which could lead to future research to modify these outcomes.Keywords: biometry, crown-rump length, pregnancy dating
