American Pregnancy Association Weekly Updates Prenatal Tests

Amniocentesis Amniotic fluid is withdrawn for testing Occurs: Weeks Reason: – Health care provider recommended following an abnormal triple test result – Identifying chromosome abnormalities, neural tube defects, and other inherited disorders Down syndrome / Trisomy 21 Accuracy: 98-99% Risk: – 1/200 women who have this procedure miscarry Due to infection of the uterus, preterm labor

Amniocentesis

Chorionic Villi Sampling (CVS) Tissue around the fetus is taken for testing Trans cervical Or Trans abdominal Occurs: During weeks Reason: – Identifying chromosome abnormalities and other inherited disorders Does not allow for testing for neural tube defects – Collects larger samples and provides faster results than amniocentesis – Provides access to DNA for paternity testing prior to delivery Accuracy: 98-99% Risk: 1/100 women who have this procedure miscarry Higher risk than an amniocentesis

Chorionic Villi Sampling

Interactive Timeline

The procedure takes about 45 minutes, although the collection of fluid takes less than five minutes Tests For: Fetal Anemia (Rh disease) assess lung maturity Spina Bifida, Down Syndrome, Cystic Fibrosis Paternity

Alpha-fetoprotein (AFP) Blood test preformed on the mother between weeks Testing for a protein that should be produced in the liver (possibility of birth defects)
