Clara Forbes · Answer 1

the answer is Chorionic Villus Sampling

Explanation:

This test is done much earlier in pregnancy, around 10 to 12 weeks instead of the usual 15 to 20 weeks. This procedure is invasive, though, since a tiny tissue from the placenta is removed and the needle is inserted through the abdomen or a catheter through the cervix. This procedure can result in miscarriage.
