Fetal screening is the screening of a fetus in the reproductive female during pregnancy. Screening happens to attempt to ascertain a prenatal diagnosis for chromosomal, congenital, or inherited syndromes. It helps inform family planning, termination, and therapeutic procedures.

Indications for fetal screening are advanced maternal age, a previously affected pregnancy, chromosomal abnormalities in either parent, a close family history of Down's Syndrome or translocation, if they are in a major risk group for cystic fibrosis, Tay Sachs, cleft lip or palate, or a history of open neural tube defects (oNTD) [1].


Fetal screening occurs by assessing maternal age, Maternal serum screening (MSS), fetal ultrasound screening, integrated prenatal screen (IPS), amniocentesis and chorionic villus sampling (CVS).
