Fetoprotein 8.2 belongs to the high value. Generally speaking, the reasons for the elevation of Fetoprotein include tumor, hepatitis B, pregnancy and so on. 1. Tumor: primary liver cancer, teratoma, lung tumor and so on may lead to high value of alpha-fetoprotein, and now alpha-fetoprotein is used as one of the indicators to judge primary liver cancer in clinic. 2. Hepatitis B: Hepatitis B is called chronic viral hepatitis B. This kind of hepatitis will lead to necrosis of liver cells and eventually develop into cirrhosis, which will cause damage to liver cells and also cause elevation of alpha-fetoprotein. 3. Pregnancy: women can also have elevated alpha-fetoprotein during pregnancy, but it will return to normal later, so there is no need to worry too much about this situation. Elevated alpha-fetoprotein usually indicates the presence of liver disease, but there is no need to panic. You need to complete the relevant examinations in a timely manner to identify the specific causes and then carry out targeted treatment.
