Alpha-fetaprotein Blood Test
When are the test done?
Screening tests are used to see what the chance is that your baby has a certain birth defect.
How is the test done?
You will need to get your blood drawn for an AFP test.
What happens if the best is positive?
If you are pregnant and your AFP level is unusually low, it could indicate that your fetus has chromosomal abnormality, such as Down or Edward’s syndrome. Abnormal AFP readings can also be due to a multiple pregnancy (having twins, triplets, etc.) or fetal death.
