Your health care provider may offer you certain tests during your pregnancy. These tests are used to make sure that you are healthy and the fetus is doing well. Some tests identify possible birth defects.
The different tests are done at certain times. Your health care provider will let you know what tests you may want or need, and when you will need them.
Some common prenatal tests for birth defects and other abnormalities include
- ultrasound
- multiple marker screening
- CVS — chorionic villus sampling
- amniocentesis
Another common test is the biophysical profile (BPP). It is most commonly given during the third trimester. The BPP uses ultrasound combined with a fetal monitor to observe fetal heartbeat and movement. BPP allows your health care provider to evaluate the well-being of the fetus.
