Tumor Markers

AFP (Alpha-Fetoprotein)

An AFP (Alpha-Fetoprotein) test measures a key liver-related tumor marker in your blood. For men, AFP is particularly relevant for monitoring liver health, especially if you have risk factors such as hepatitis or heavy alcohol use. Take control of your health by understanding this important marker. This test alone cannot diagnose cancer and must be interpreted by a healthcare professional alongside other findings.

Doctor's Assessment Included

Reference Ranges

No established reference range

There is no generally applicable reference interval for AFP. The result depends on the assay: Dutch laboratories publish upper limits of 7 to 9 µg/l, while the NVKC states roughly 20 µg/l — a difference that decides whether the same value is called normal or raised. The NVKC itself says: "never interpret AFP results from different laboratories interchangeably". Our laboratory sends samples to several partner laboratories, each with its own analyser and its own reference values. Your own result therefore arrives with the reference interval of the laboratory that examined your blood: that is the interval that applies to you. Discuss your result with your doctor; we do not state a number that may not apply to you.

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

What It Measures

This test measures the concentration of alpha-fetoprotein (AFP) in your blood. AFP is a glycoprotein produced by the fetal liver and yolk sac during pregnancy. In healthy non-pregnant adults, AFP levels are typically very low. The test is used as a tumor marker, primarily to monitor liver health and to support the evaluation of certain germ cell tumors, but it is not a standalone diagnostic tool.

Why It Matters

Monitoring AFP levels can be important for individuals with known liver conditions or those being evaluated for certain tumors. Elevated AFP may be associated with hepatocellular carcinoma (liver cancer), germ cell tumors, or benign conditions such as chronic liver disease, hepatitis, or cirrhosis. However, elevated levels do not necessarily indicate cancer, and normal levels do not rule it out. Results should always be interpreted by a healthcare professional alongside other diagnostic tests and clinical information.

When to Test

AFP testing may be recommended if you have chronic liver disease, hepatitis B or C, cirrhosis, or are being monitored for liver cancer or germ cell tumors. Your healthcare professional may also request this test as part of a broader evaluation. Consult a healthcare professional for guidance on whether this test is appropriate for your situation.

Symptoms

High Levels

Elevated AFP levels may be associated with liver conditions such as hepatocellular carcinoma, hepatitis, or cirrhosis, as well as certain germ cell tumors. Elevated levels can also occur during pregnancy. However, elevated AFP does not necessarily indicate cancer and may have many other explanations. Always consult a healthcare professional for proper interpretation.

Lifestyle Tips

Maintain a healthy lifestyle to support liver health: limit alcohol consumption, eat a balanced diet rich in fruits, vegetables, and whole grains, maintain a healthy weight, exercise regularly, avoid tobacco use, and attend regular health check-ups. If you have chronic liver disease, follow your healthcare professional's recommendations for monitoring and treatment.

Frequently Asked Questions

Can an AFP test diagnose cancer?
No, an AFP test alone cannot diagnose cancer. It is one tool among many that healthcare professionals use. Elevated AFP levels can be caused by various conditions, including benign liver disease, hepatitis, cirrhosis, and pregnancy. Your healthcare professional will interpret the results alongside other diagnostic tests and clinical findings.
What conditions can cause elevated AFP levels?
Elevated AFP may be associated with hepatocellular carcinoma (liver cancer), germ cell tumors, chronic hepatitis, cirrhosis, and pregnancy. Some individuals may have mildly elevated levels without any significant underlying condition. A healthcare professional should evaluate the results in context.
Can AFP levels be elevated even if I do not have cancer?
Yes, AFP levels can be elevated in many non-cancerous conditions, including chronic liver disease, hepatitis, cirrhosis, and pregnancy. This is why the test is not used as a standalone diagnostic tool. Your healthcare professional will consider the full clinical picture when interpreting your results.
