What this test is
The Alpha-Fetoprotein (AFP) tumor marker test is a blood test that measures the amount of AFP, a protein normally produced by the liver and yolk sac in a developing fetus. In adults, elevated AFP levels can be associated with certain cancers, such as liver, testicular, or ovarian cancer, as well as non-cancerous liver diseases.
What it measures
- Alpha-Fetoprotein (AFP) — reflects the level of this protein in the blood, which can be elevated in certain cancers and liver conditions
What the test involves
The test involves a standard blood draw from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order an AFP test to help diagnose or monitor certain types of cancer, particularly liver cancer or germ cell tumors. It may also be used to assess treatment response or detect recurrence.
Preparation

Frequently asked questions
What can cause elevated AFP levels?
Elevated AFP levels can be caused by liver cancer, testicular cancer, ovarian cancer, or non-cancerous liver conditions such as cirrhosis or hepatitis. Pregnancy also normally raises AFP levels. Your healthcare provider can help interpret what your specific result might mean.
Is the AFP test used to screen for cancer in healthy people?
The AFP test is not typically used as a general screening test for cancer in people without symptoms or risk factors. It is most often used in people with a known or suspected cancer or liver disease. Your healthcare provider can determine if this test is appropriate for you.
How often should I have an AFP test?
The frequency of AFP testing depends on your individual medical situation and your healthcare provider's recommendations. It may be done periodically to monitor treatment or check for recurrence. Follow your provider's guidance for scheduling.
Can I eat or drink before an AFP test?
