Screening for trisomy 18 by maternal age, fetal nuchal translucency, free β‐human chorionic gonadotropin and pregnancy‐associated plasma protein‐A

2008-08-22

Abstract excerpt

Abstract Objectives To derive a model and examine the performance of first‐trimester screening for trisomy 18 by maternal age, fetal nuchal translucency (NT) thickness, and maternal serum free β‐human chorionic gonadotropin (β‐hCG) and pregnancy‐associated plasma protein‐A (PAPP‐A). Methods Prospective combined screening for trisomy 21 was performed at 11 + 0 to 13 + 6 weeks in 56 893 singleton pregnancies, includ...
