Identify and describe three tests used to assess the health of an unborn baby
What will be an ideal response?
A good answer would include the following key points:
1 . An amniocentesis can be performed between the 15th and 20th week of pregnancy. This procedure examines a sample of amniotic fluid, which contains fetal cells. This test can identify a variety of genetic defects and can determine the sex of the child.
2 . Chorionic villus sampling (CVS) can be performed between 8 and 11 weeks. This procedure involves inserting a thin needle into the fetus and extracting small samples of hair-like material that surrounds the embryo.
3 . Ultrasound sonography uses very high- frequency sound waves to detect structural abnormalities or multiple pregnancies, measure fetal growth, judge gestational age, and evaluate uterine abnormalities. It can also be used as an adjunct to other procedures, such as amniocentesis.
