Alpha-fetoprotein 11.4ng/mL is normal, normal human serum alpha-fetoprotein level should be less than 25ng/mL, so 11.4ng/mL is within the normal value, there is no need to worry too much. Alpha-fetoprotein is a glycoprotein, belonging to the albumin family, and is mainly synthesized by fetal hepatocytes and yolk sacs, so it has a high concentration in fetal blood circulation. After the birth of the fetus, alpha-fetoprotein decreases, so the level of alpha-fetoprotein in adult serum is extremely low, with a normal value of less than 25 ng/mL, so 11.4 ng/mL is a normal level. Mild elevation of serum alpha-fetoprotein can be seen in acute hepatitis, chronic hepatitis, cirrhosis and other diseases. Serum alpha-fetoprotein can be significantly elevated if one suffers from liver cancer, testicular cancer, ovarian tumor, malignant teratoma, pancreatic cancer, stomach cancer, intestinal cancer, lung cancer and other diseases. If the examination finds that the alpha-fetoprotein is 11.4ng/mL, there is no need to worry too much, cooperate with the doctor to improve other examinations.
