Can the results of the triple screen test indicate that the fetus has defects?

Patient's question:

Patient: Female 19 years old In good health

Doctor's answer:

The screening test is safe and convenient, posing no risk to either the pregnant woman or the fetus. The test involves analyzing the concentration of alpha-fetoprotein (AFP) and human chorionic gonadotropin (β-hCG) in the pregnant woman's blood, so only a small blood sample is needed for the test, which is completely safe.
