Alpha-fetoprotein 7.46μg/L is normal. AFP is secreted by the liver and the yolk sac of the embryo, and is basically suppressed after birth. It is an important indicator for the clinical diagnosis of primary liver cancer, and the normal value is less than 25ug/L. AFP 7.46μg/L suggests that it is within the normal range. Elevated alpha-fetoprotein has two kinds of conditions: physiological and pathological. 1. Physiological elevation: it is seen in pregnant women, caused by the secretion of alpha-fetoprotein by newborn naive liver cells of the fetus to enter the blood of the mother through umbilical cord blood, which is a normal phenomenon and usually occurs in the third to fourth month of pregnancy, and returns to normal in about 3 weeks after delivery. 2. Pathological elevation: seen in hepatocellular carcinoma, hepatoblastoma, gonadal teratoblastoma, testicular cancer and other tumors, or patients with hepatitis, generally benign disease is a transient increase, lasts for 2~3 weeks, and malignant disease is a persistent increase, greater than 400ug/L, and combined with the history of chronic hepatitis accompanied by nausea and other gastrointestinal symptoms. It is recommended that patients with abnormal alpha-fetoprotein results go to a regular hospital in time to improve the relevant examinations to clarify the cause of the disease, and standardize the treatment under the guidance of the doctor, so as not to delay the condition.
