Alpha-fetoprotein 6.82 μg/L is within the normal range. Alpha-fetoprotein is a glycoprotein produced by embryonic hepatocytes and yolk sacs, and is one of the main indicators of liver malignancy in clinical diagnosis. The normal range of enzyme-linked immunosorbent assay (ELISA) is 0-25 μg/L. The low positive concentration is 25-400 μg/L, and the high positive concentration is more than 400 μg/L. The higher the value is, the higher the chance of liver malignancy, so the alpha-fetoprotein 6.82 μg/L is normal. Alpha-fetoprotein can monitor the signals of some diseases in time. If the value of alpha-fetoprotein is elevated, it may be a signal of certain diseases, such as liver cancer, germ cell cancer, stomach cancer, colon cancer, pancreatic cancer and other tumors, and also can be seen in hepatitis, cirrhosis and other diseases. When liver cells become cancerous, it will raise the serum alpha-fetoprotein, which may gradually rise as the condition worsens. The diagnostic value of alpha-fetoprotein >400μg/L is high for primary liver cancer, but alpha-fetoprotein is normal in a minority of liver cancers. Therefore, one cannot diagnose or exclude a certain disease only based on high alpha-fetoprotein, and it is also necessary to combine with other imaging or pathological examinations to make a clear diagnosis. If alpha-fetoprotein is normal, but there are other symptoms such as abdominal distension, abdominal pain, nausea, etc., or alpha-fetoprotein is elevated, it is recommended to consult a doctor in time, complete relevant examinations, clarify the cause of the disease, and treat it positively, so as to avoid misunderstanding of the disease.
