What is first trimester screening?
http://www.ntdlabs.com/ First Trimester Screening (Ultra-Screen) includes ultrasound measurement of the nuchal translucency with a maternal blood test for pregnancy associated plasma protein-A and free Beta human chorionic gonadotropin. About 90% of babies with Down syndrome and Trisomy 18 will have a high-risk result. Other chromosome abnormalities may also cause a high-risk result. A low risk result does not eliminate the possibility that the baby may have Down syndrome, Trisomy 18, other chromosome problems, birth defects or mental retardation. Most parents learn that they are at low risk for Down syndrome and Trisomy 18 and appreciate receiving this reassurance. Parents with high risk results are offered genetic counseling and further testing to determine if there baby has a chromosome abnormality or not. Tests such as chorionic villus sampling (CVS) and amniocentesis are performed by board certified perinatologists at Capital Health.
