AFP 3.3 is a blood level of 3.3 ug/L, which is within the normal range. The reference value for alpha-fetoprotein is 25 ug/L or less.
Alpha-fetoprotein is synthesized by the liver and yolk sac, and its synthesis is inhibited after fetal birth. When malignant lesions are present in the hepatocytes or embryonic tissues of the gonads, the synthesis of alpha-fetoprotein is restarted, resulting in a marked increase in blood levels, thus making alpha-fetoprotein clinically valuable in the diagnosis of hepatocellular carcinoma.
In about half of the patients with primary hepatocellular carcinoma, the alpha-fetoprotein is higher than 300ug/L; in viral hepatitis and cirrhosis, it is also elevated to varying degrees, and is usually below 300ug/L.
If abnormal results of alpha-fetoprotein test occur, it is recommended to consult a doctor in time to clarify the cause of the disease and carry out targeted treatment or therapy with the help of a doctor.
