What is an alpha-fetoprotein (AFP) test?

ANSWER

Usually, you have a very small amount of alpha-fetoprotein (AFP) in your body. But when you have liver disease, some types of cancer, or are pregnant, you'll usually have more of it in your blood. An AFP tumor marker test checks the level of this protein.

A higher AFP level doesn't always mean you have a health problem. Some people simply have more AFP than is typical.
