fetal chromosomal abnormalities.他们做不了，要去另一个医生处做。让自己联系保
险公司，问保险是否cover，我的保险是bcbs bluechoice heathcare plus HMO，在佐
治亚州。
总共四种测试方式：1. chorionic villus sampling. 2. amniocentesis. 3. quad
screen. 4. first trimester screen.
3. quad screen. 4. first trimester screen.都是测什么东西？ 那种对胎儿最安全？
谢谢

发帖数: 872 | 2 The quad screen is done in the second trimester, usually between 15 and 18
weeks of pregnancy. Ideally, the test should be performed in conjunction
with first-trimester screening tests. This combination is known as
integrated or sequential screening. But if you miss the opportunity to start
your screening in the first trimester, the quad screen alone can still give
you some good information.
3.4种都是抽血，都安全。
3是孕中期抽血，4是孕早期，你家属第13周第2天，可能能赶上4的末班车，最好是抽两
次血结合看准确率高些。 | q****3
