A triple screen is a blood test that measures three things called alpha-fetoprotein, human chorionic gonadotropin and unconjugated estriol. The results of the blood test can help your doctor see if your baby may be at higher risk for certain birth defects such as Down syndrome and neural tube defects. 8 ^! r' D+ b! h! `9 i l! _8 L/ e7 B8 M

另外,即便检查的结果为唐氏Positive,也不代表孩子真的会是唐氏宝宝,需要做羊水穿刺做进一步的检查。通常false positive的比较多。* d8 f0 U; v G8 H. N3 E+ Q
