Junie is in her second trimester and has just had the triple screen test. What is this test, and what problems in the fetus should Junie expect the test to diagnose?
What will be an ideal response?
The ideal answer should include:
1. The triple screen test is a blood test given to the mother between the 15th and 20th weeks of the pregnancy.
2. The test measures levels of alpha-fetoprotein (AFP), a protein produced by the fetus; human chorionic gonadotropin (hCG), a hormone produced within the placenta; and estriol, an estrogen produced by both the fetus and the placenta.
3. The test can detect 75 to 90 percent of babies with neural tube defects.
4. If the blood test produces an abnormal result, further testing can reveal more than 100 conditions in the fetus, such as single-gene disorders, muscular dystrophy, and Down syndrome.
