Abstract
A method for antenatal screening for chromosomal and other abnormalities in an unborn child is determined by measuring the gestational age discrepancy of the pregnant mother. This data is determined (a) by reference to the last menstrual period, and (b) a biometric measurement of the fetus. The difference between the ages as determined using (a) and (b) is calculated. This calculated difference is then examined using reference data to determine fetal abnormalities. These data can also be used with assay of maternal fluids for various pregnancy markers.
