We investigated the accuracy of using symphysis pubis-fundal height measurement and ultrasonically derived estimation of fetal weight for identifying small-for-gestational-age (SGA) and large-for-gestational-age (LGA) fetuses. A retrospective cohort study was performed using computerised records of all non-diabetic women referred for an ultrasound growth scan (US) with clinically suspected SGA or LGA singleton fetuses from 35 weeks’ gestation between October 2008 and March 2009 (n?=?185). Birth weight data were also collected for all births over the study period (n?=?3200). One-third (34%) of ultrasound estimated fetal weights were inaccurate by >10%. However, an inaccurate ultrasound estimation did not significantly increase the likelihood of spontaneous or induced onset of labour or delivery by caesarean section. Most (79%) growth scans were performed on well-grown fetuses. The majority (80%) of SGA and LGA babies in our cohort were not identified by clinicians during routine antenatal care. From 3,200 live births, there were a total of 59 infants weighing
