The risk can be estimated based on maternal age, prenatal genetic testing of fetal DNA, various maternal lab tests, and fetal nuchal translucency or nuchal fold measurements. RESULTS: The median maternal age was 28.6 years. This was a multicenter study of screening for trisomy 21 by a combination of maternal age, fetal NT and maternal serum free beta-hCG and PAPP-A at 11-14 weeks of gestation, using the methodology developed by the Fetal Medicine Foundation. The distribution of estimated risks for trisomy 21 was determined and the sensitivity and false-positive rate for a risk cut-off of 1 in 300 were calculated.

The risk of trisomy 21 is directly related to maternal age. Soft markers or anomalies on an 18-20 week ultrasound increase the risk for aneuploidy and should be interpreted in conjunction with the prenatal screening (SIPS, IPS, or Quad) … Down syndrome (trisomy 21) is the most commonly recognized genetic cause of mental retardation. | Kagan KO, Wright D, Baker A, Sahota D, Nicolaides KH.

Spencer K, Souter V, Tul N, Snijders R, Nicolaides KH. In total, 3864 singleton pregnancies with live fetuses at 11-14 weeks were examined and the fetal NT and maternal serum free beta-hCG and PAPP-A were successfully measured in all cases. 2017 Mar 15;3(3):CD012600. The blood samples were collected at outpatient clinics in serum separator tubes containing a polymer gel and clot activator (Becton Dickinson), very often 1–2 weeks preceding the ultrasound investigation. Screening was performed in 7,096 singleton pregnancies. In Germany, the results of screening for chromosomal defects by measurement of fetal NT and maternal serum biochemistry, in centers with appropriately qualified sonographers, are similar to those reported in the UK using the same methodology. - BabyCenter India The risk for Down syndrome increases with increasing maternal age. « Le dépistage prénatal a pour but d’évaluer le risque, pour l’enfant à naître, d’être porteur de trisomie 21. Trisomy 21, also called Down syndrome, is caused by the presence of three copies of either the entire chromosome 21 or a crucial region of chromosome 21 in each cell rather than two. It is predicted to remain below 4% at least until 2007; to achieve a 5% FPR in 2007 the risk limit 1 in 400 is proposed. Another risk like neural tube defect & trisomy 18 is low. Cicero S, Bindra R, Rembouskos G, Spencer K, Nicolaides KH. NLM Falcon O, Auer M, Gerovassili A, Spencer K, Nicolaides KH. We believe the risk limit should be specifically estimated for each country based on its population distribution of maternal age. | The only result that varies is the percentage of screen positive patients at the risk limit 1 in 300.
