AFP 11.6ng/ml is not considered serious and is within the normal reference range. Fetoprotein is a kind of tumor marker, which is closely related to liver cancer and many other tumors. If the concentration of alpha-fetoprotein in the serum is elevated, it means that the body may have an abnormality or even a tumor. AFP is an important serum tumor marker for the adjuvant diagnosis and treatment of primary liver cancer. The normal reference range of alpha-fetoprotein is <25. Generally speaking, if the concentration of alpha-fetoprotein is >400ng/ml, the possibility of primary liver cancer is higher. If the alpha-fetoprotein is 11.6ng/ml, don’t worry, it is normal. If the alpha-fetoprotein is abnormally elevated, it is recommended to consult a doctor in time.
