A 37-year-old woman agrees to have a prenatal test done in order to diagnose fetal defects. There is a history of Down syndrome in her family. Which invasive prenatal test provides the earliest diagnosis and rapid test results?

Respuesta :

Answer:

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.
