Serum alpha-fetoprotein variants

Alpha-fetoprotein heterosomes are of great significance in the differential diagnosis of primary liver cancer and benign liver disease (acute, chronic hepatitis, cirrhosis, etc.) with elevated AFP. Alpha-fetoprotein is a glycoprotein, English abbreviation AFP. Under normal circumstances, this protein mainly comes from the liver cells of the embryo. Alpha fetoprotein disappears from the blood about two weeks after the fetus is born, so the alpha fetoprotein content in normal human serum is less than 20 micrograms / liter. However, when the liver cells became cancerous, the function of producing this protein was restored, and its content in the serum would increase sharply as the disease deteriorated. Alpha-fetoprotein became a specific clinical diagnosis of primary liver cancer. index
