FMF FIRST TRIMESTER SCREEN

Aneuploidies are major causes of perinatal death and childhood handicap; maternal serum screening test is effective screening method for detection of major aneuploidies (Trisomy 21 & Trisomy 18/13) in the first trimester of pregnancy. Screening by a combination of fetal nuchal translucency and maternal serum free-β-human chorionic gonadotrophin & pregnancy-associated plasma protein-A can identify about 90% of fetuses with trisomy 21 and other major aneuploidies for a false-positive rate of 5%. The performance of first-trimester screening is further improved by inclusion of the nasal bone and flow in the ductus venosus & across the tricuspid valve in the risk assessment.
