Glycoconjugate Antigen 72-4 test of 11.1 U/ml is higher than normal value, comprehensive examination and regular review are recommended. Glycoantigen 72-4 (CA72-4) is a tumor-associated glycoprotein, a marker for gastrointestinal and ovarian tumors. Normal human serum CA72-4 ≤ 6.9 U/ml. elevation is mainly seen in digestive tract tumors, such as gastric cancer, colon cancer, some gynecological tumors, such as ovarian cancer, lung malignant tumors, and some benign diseases, such as cirrhosis of the liver, rheumatism, pneumonia, pancreatitis and so on. Elevated glycoantigen 72-4 index does not prove that one has a tumor, but needs to be combined with other tumor markers and imaging results for comprehensive evaluation. For example, the combination of serum CA724 and CEA (carcinoembryonic antigen) can improve the sensitivity and specificity of diagnosing gastric cancer, and the combination of CA724 and CA125 can improve the detection rate of ovarian cancer. If the value of Glycoantigen 72-4 is mildly elevated and the test does not reveal any substantial lesions in the body organs, the test can be repeated periodically to dynamically monitor the changes in the value.
