What Is The AFP Tumor Marker?
AFP, or alpha-fetoprotein, is a protein that is normally produced by the liver, yolk sac, and gastrointestinal tract of a developing foetus. In adults, AFP levels are typically low, but elevated levels can indicate certain medical conditions.
Why Is It Important?
Medical professionals use the AFP tumor marker primarily for the following reasons:
- Liver Cancer Detection – One of the most common uses of the AFP test is to help detect hepatocellular carcinoma (HCC), the most prevalent type of liver cancer.
- Monitoring Liver Diseases – Individuals with chronic liver diseases such as hepatitis B, hepatitis C, or cirrhosis may undergo AFP testing to monitor their risk of liver cancer.
- Germ Cell Tumour Diagnosis – AFP levels may be elevated in certain germ cell tumours, such as testicular or ovarian cancers.
- Assessing Treatment Response – If an individual is receiving treatment for liver cancer or a germ cell tumour, AFP levels can indicate whether the therapy is effective.
What Can Affect AFP Levels?
Several factors can influence AFP levels, including:
- Pregnancy – Pregnant women naturally have higher AFP levels as the protein is produced by the foetus.
- Liver Conditions – Conditions such as liver cirrhosis and chronic hepatitis can cause moderate increases in AFP levels.
- Cancer – Liver cancer and certain testicular or ovarian cancers can cause significant increases in AFP levels.
When Should You Get Tested For AFP?
Your doctor may recommend an AFP tumor marker test if you:
- Have chronic hepatitis B or C and are at risk of liver cancer.
- Show symptoms suggestive of liver cancer, such as unexplained weight loss, jaundice, or abdominal pain.
- Are undergoing treatment for liver or germ cell cancers and need to track your response.
- Have a family history of liver cancer and require regular screening.

What Do Your Results Mean?
AFP levels are measured in nanograms per millilitre (ng/mL). The normal range varies between laboratories, but typically:
- Less than 10 ng/mL or up to 40ng/mL – Considered normal for most adults.
- More than 400 ng/mL – May be associated with liver cancer or tumours.
It is important to remember that an elevated AFP level does not automatically mean you have cancer. Your doctor will consider your medical history, symptoms, and other test results before making a diagnosis.
