AFP of 14 ng/mL is normal. Alpha-fetoprotein, or AFP, is a glycoprotein that has a high concentration in the fetal circulation but declines after birth and is replaced by albumin, so adult serum levels of alpha-fetoprotein are extremely low. The normal range for alpha-fetoprotein should be less than 25 ng/mL, so an alpha-fetoprotein of 14 ng/mL is normal. Alpha-fetoprotein is more closely related to the occurrence and development of hepatocellular carcinoma as well as a variety of other tumors, and is able to show high concentrations in a variety of tumors. Therefore, elevated serum alpha-fetoprotein in adults can be seen in liver cancer, testicular cancer, ovarian tumor, gastric cancer, pancreatic cancer, etc. It can also be seen in acute and chronic hepatitis, cirrhosis and other diseases. When abnormal alpha-fetoprotein value occurs, it is recommended to go to the hospital in time for consultation and active treatment.
