Question

Neural tube defects are detected during prenatal care by elevated alpha-fetoprotein (AFP) levels in the amniotic fluid and maternal blood, with the exception of spina bifida occulta. What is the purpose of measuring AFP levels in prenatal care?

1) To diagnose neural tube defects
2) To monitor the progress of the pregnancy
3) To determine the gender of the baby
4) To detect other genetic abnormalities

Answer 1

Measuring alpha-fetoprotein (AFP) levels in prenatal care is used to diagnose neural tube defects.

Step-by-step explanation:

The purpose of measuring alpha-fetoprotein (AFP) levels in prenatal care is to diagnose neural tube defects. Neural tube defects, such as spina bifida and anencephaly, can be detected by elevated AFP levels in the amniotic fluid and maternal blood. However, it is important to note that AFP levels can only diagnose neural tube defects and not other genetic abnormalities or monitor the progress of the pregnancy.
