Screening for triploidy by the risk algorithms for trisomies 21, 18 and 13 at 11 weeks to 13 weeks and 6 days of gestation

27 Nov 2008

Abstract excerpt

OBJECTIVES: To examine the effectiveness in screening for triploidy at 11 weeks to 13 weeks and 6 days of gestation by the combined use of the risk algorithms for trisomies 21, 18 and 13 based on maternal age, fetal nuchal translucency (NT) thickness, fetal heart rate (FHR) and maternal serum free beta-hCG and PAPP-A. METHODS: Prospective screening for trisomy 21, including 56 376 normal singleton pregnancies and...
