What is considered a normal AFP value?

What is considered a normal AFP value?

• A. >50 ng/mL
• B. 100 ng/mL
• C. <10 ng/mL
• D. 0 ng/mL

Answer: (C)

Alpha-fetoprotein (AFP) is a protein produced mainly by the fetus (yolk sac and liver), and it drops to very low levels after birth. In healthy nonpregnant individuals, the AFP value is normally very low, with a typical adult reference range of less than 10 ng/mL. Values higher than this are not considered normal and may indicate issues such as liver disease, hepatocellular carcinoma, or certain germ cell tumors, warranting further evaluation. A value of 0 ng/mL isn’t physiologically expected in standard testing, so the normal range is better characterized as under 10 ng/mL.
