This operation manual was used to implement the Fetal Growth Longitudinal Study (FGLS), which involved screening healthy women between 9 and 14 weeks gestation at the time of their early antenatal visit, and followed-up with standard clinical and 2D ultrasound examinations every 5 weeks, i.e. up to six times during a term pregnancy. The results of the FGLS inform new, international fetal and newborn growth standards and a package of supportive tools, guidelines and resources, including a new international equation for estimating gestational age through ultrasound.
