The increased level of an alpha-fetoprotein indicates the presence of either a germ cell tumour or primary liver cancer.

This test is usually used to check the level of alpha-fetoprotein in the blood of pregnant women. This test is done to know about the baby’s risk for certain genetic problems and birth defects.
What is the normal level of alpha-fetoprotein?
Healthy adults: 0-8ng/mL
The average range will vary with pregnant women.

Low alpha-fetoprotein levels may also mean that the baby has a genetic disorder such as Down syndrome, a genetic problem that causes intellectual disabilities and health problems.
What does the high alpha-fetoprotein mean?
High alpha-fetoprotein levels may indicate the baby has an increased risk of neural defect tube such as:
- Spina bifida: In which the bones of the spine do not close around the spinal cord.
