AFP
A tumor-marker test used as part of a broader clinical picture. This test does not diagnose or rule out cancer on its own.
About this test
AFP can be used with imaging in selected liver-cancer surveillance programs or to monitor certain known tumors.
Common reasons for testing
- Clinician-directed liver surveillance for eligible high-risk patients.
- Monitoring selected known cancers.
These are examples of clinical uses. Your history and symptoms determine whether testing is appropriate.
What to expect
A small blood sample is taken from a vein in your arm. You may feel a brief pinch and have mild bruising. Tell the person collecting your sample if you have fainted with needles or take a blood thinner; keep pressure on the site afterward.
Appointment length
Your visit is expected to take about 15 minutes at our West Ashley location.

Preparation
- Fasting is not usually needed for this test alone. If other tests are being collected, confirm their instructions before your visit.
- Bring a list of medicines and supplements, including biotin, vitamins, and hormones. Do not stop or change prescribed medicines unless your clinician tells you to.
Order requirement
No outside order needed
Understanding your results
- AFP alone neither diagnoses nor excludes cancer. Pregnancy and noncancer liver conditions can raise it.
- This tumor-marker test is not interchangeable with a gestational-age-specific prenatal AFP screen.
What happens next?
Review the report with your clinician alongside your symptoms, medical history, and earlier results. A value outside the reference range does not always mean disease, and a normal result does not explain every symptom. Confirm who will arrange any repeat or additional testing.
