Amniocentesis is a prenatal procedure that your doctor may recommend you have during pregnancy. The test checks for fetal abnormalities (birth defects) such as Down syndrome, cystic fibrosis or spina bifida. In most cases, the results are normal. Amniocentesis is performed between 16 and 20 weeks into the pregnancy.
So, what causes miscarriage after amniocentesis?
Miscarriage. It's not known for certain why amniocentesis can lead to a miscarriage. But it may be caused by factors such as infection, bleeding or damage to the amniotic sac that surrounds the baby. Most miscarriages that happen after amniocentesis occur within 3 days of the procedure.
Also Know, when can an amniocentesis be done?
Genetic amniocentesis is usually done between weeks 15 and 20 of pregnancy. Amniocentesis done before week 15 of pregnancy has been associated with a higher rate of complications. You might consider genetic amniocentesis if: You had positive results from a prenatal screening test.
Why is amniocentesis done at 15 weeks?
Amniocentesis before 15 weeks is considered as early amniocentesis. Before 15 weeks of pregnancy, the amount of amniotic fluid levels is lower. This makes it more difficult to obtain enough amniotic fluid for testing.
What amniocentesis Cannot detect?
Because ultrasound is performed at the time of amniocentesis, it may detect birth defects that are not detected by amniocentesis (such as cleft palate, cleft lip, club foot, or heart defects). There are some birth defects, however, that will not be detected by either amniocentesis or ultrasound.
