Elevated alpha-fetoprotein with normal liver function may be caused by physiological factors such as pregnancy or pathological factors such as cirrhosis and liver cancer. 1. Physiological factors: pregnant people may have mild elevation of alpha-fetoprotein with normal liver function, and it will increase with the increase of pregnancy months, but it will gradually decrease after delivery. 2. Pathological factors: patients with cirrhosis and early stage of hepatocellular carcinoma may have elevated alpha-fetoprotein even though their liver function is not significantly affected. If the liver function is normal but the alpha-fetoprotein is elevated, it is recommended to go to the hospital if physiological factors are ruled out or if the alpha-fetoprotein is seriously elevated during pregnancy.
