Alpha-fetoprotein 13.36ng/mL, reference value 0-7ng/mL, may be a normal manifestation of pregnancy, or it may indicate the presence of liver or gonadal embryonic tumors and other diseases. Fetoprotein is often used as a tumor marker, and its elevation can be seen in malignant diseases such as primary liver cancer, embryonal gonadal cancers such as ovarian cancer, testicular cancer, teratoma, etc., as well as gastric cancer, pancreatic cancer and other diseases. It can also be seen in benign diseases such as viral hepatitis and cirrhosis, as well as in women during normal pregnancy. Therefore, there is no need to be overly nervous when alpha-fetoprotein is elevated, it should be retested, and imaging pathology and other examinations can be improved to clarify the diagnosis and targeted treatment. It is recommended to consult a doctor for standardized diagnosis and treatment when necessary.
