Glycoantigen 125 value 124 is considered high. Glycoantigen 125 is a kind of tumor marker, and the value of normal serum Glycoantigen 125 is less than 35U/ml for men and less than 40μg/L for women, which is commonly used in the detection of ovarian cancer, observation of treatment effect and judgment of recurrence, as well as assisting in the diagnosis of other tumors, such as endometrial cancer, cervical cancer, etc., which may lead to the increase of Glycoantigen 125. However, the specificity of the elevation of GAC 125 is limited, and the elevation is not necessarily cancerous. There are some benign diseases that can also cause the elevation of GAC 125, such as pelvic inflammation, benign ovarian diseases, uterine fibroids, endometriosis, abdominal inflammation, as well as cirrhosis of the liver and diabetes mellitus, etc., which may also lead to an increase in the value of GAC 125. Elevated Glycoantigen 125 is a sign that the body may be suffering from certain diseases, and it is necessary to go to the hospital in a timely manner to determine the cause of the disease, and to provide timely and appropriate treatment to avoid delays in the disease.
