25

Discussion Question 5b Answer: What types of fetal anomalies can be detected by

an AFP assay of maternal serum? Explain. What is the significance of the AFP levels?

Answer: Neural tube defects are indicated by high levels of AFP. Low levels of AFP may indicate Down syndrome.

For indications of neural tube defects, ultrasonography would be performed. For indications of Down Syndrome, chromosomal studies would be performed.
