An alpha-fetoprotein of 29ug/L is abnormal and mildly high; the normal range for alpha-fetoprotein is 0 to 25ug/L.
In healthy individuals, synthesis of alpha-fetoprotein is inhibited and serum levels are extremely low. Elevation is seen in liver cancer, stomach cancer, pancreatic cancer, embryonic tumor of the gonads, cirrhosis and other diseases, when malignant changes occur in hepatocytes or embryonic cells of the gonads, which resynthesize the alpha-fetoprotein. However, elevated alpha-fetoprotein alone cannot confirm the diagnosis, and needs to be combined with specific conditions and other test results.
Elevated alpha-fetoprotein can also be seen in pregnant women and infants from 1 to 3 months of age, because the liver and yolk sac can synthesize alpha-fetoprotein in the early stages of the fetus, and it can return to normal 3 weeks after delivery, and it can return to normal in infants from 2 to 3 months of age.
It is recommended that patients with abnormal alpha-fetoprotein go to regular hospitals for timely consultation and standardized treatment under the guidance of doctors to avoid delaying the condition or causing adverse reactions.
