first, the fetus is at least 24 weeks gestational age (GA), with GA based on certain
last menstrual period (LMP) date with confirmatory first or second trimester ultrasound
(US) scan, OR uncertain LMP with second trimester ultrasound, intrauterine insemination
(IUI), OR embryo transfer, OR certain or uncertain LMP with fundal height and no confirmatory
first or second trimester scan; second, HC 2 SD below mean or less than 3 percentile
according to fetal US scan using appropriate standardized reference charts according
to GA and gender for the population (e.g., WHO growth reference charts if GA greater
than or equal to 37 weeks and Intergrowth-21st reference charts for GA 24-36 weeks);
third, HC at birth or autopsy is in the normal range using appropriate standardized
reference charts according to GA and gender for the population, which means that this
