What week did you find out your baby had down syndrome through ultrasound?

Screening for Down's: Due to its late timing (18 to 20 weeks of gestation), the genetic sonogram is not appropriate as a primary screening test.The first trimester combined test is the best screening test for women whose priorities include privacy and early diagnosis. This test involves combining data from the ultrasound with certain serum marker results. It can be performed at 9-13 weeks gestation.

Wrong approach: Thickened umbilical cord along with abnormal triple screening is suggestive of down syndrome. Definitive prenatal diagnosis of Down syndrome can only be made by chromosome study of cells obtained by amniocentesis or chorionic villi sampling. Consult your obstetrician for further details.

Down's Screening: Full intergrated test consists of ultrasound measurement of nuchal translucency at 10 to 13 weeks combined with other test for serum markers has the detection rate of 85 to 95 percent and the lowest false positive rate for Down's syndrome screening tests
