Alpha-Fetoprotein (AFP) Tumor Marker Test in Minnesota

The alpha-fetoprotein (AFP) tumor marker test measures the level of AFP in your blood. AFP is a protein normally made by a developing fetus, but it can also be produced by certain cancers, so doctors order this test to help detect or monitor some tumors.

What it measures

Alpha-fetoprotein (AFP) — The main protein measured; high levels can be a sign of certain cancers or liver conditions.
Total AFP — The overall amount of AFP in your blood, without separating different forms.
AFP-L3% — Sometimes measured to see what portion of AFP is a specific subtype linked to liver cancer.

Who it is for

Doctors typically order this test for people with known or suspected liver cancer, testicular cancer, or ovarian cancer, and for those with chronic liver disease who are at higher risk.

Preparation

No special preparation is usually needed. You can eat and drink normally before the blood draw, and no fasting is required.

Results and what they mean

Results are reported as a number, often in nanograms per milliliter (ng/mL), along with a reference range from the lab. Your clinician interprets the result based on your medical history, symptoms, and other tests. This information is not medical advice; only your healthcare provider can explain what your results mean for you.

Frequently asked questions

Is this test used to screen for cancer in everyone?

No. It is mainly used for people with a known or suspected tumor or those at higher risk due to liver disease. It is not a general screening test for all cancers.

Can a high AFP level mean I definitely have cancer?

No. AFP can be elevated in other conditions, such as liver inflammation or pregnancy. Your doctor will consider other tests to make a diagnosis.

How often should I have this test?

Your doctor will decide how often based on your situation. It may be repeated to monitor treatment or check for recurrence.

Does pregnancy affect AFP results?

Yes. AFP is naturally high during pregnancy, so the test is interpreted differently for pregnant women. Tell your doctor if you are pregnant.
