Glycoconjugate antigen 72-4 is CA72-4, which is a blood tumor marker often used in medical checkups, but this blood tumor marker is not very specific and often shows elevated test results even in non-tumor people, which is the so-called false positive. The main causes of this condition are as follows: 1. drugs, some specific drugs, especially anti-gout drugs, such as colchicine, and non-steroidal anti-inflammatory drugs, such as ibuprofen, can cause high CA72-4, and some herbal medicines, some of which can also cause a transient increase in CA72-4. 2. common causes of high glycoconjugate antigen 72-4, are The patient has inflammatory diseases, some chronic inflammatory diseases, will also cause CA72-4 high, like the common chronic gastritis, colitis. 3, benign gynecological diseases, including pelvic inflammatory disease, as well as rheumatic immune system diseases, will also have this index high. 4, there is a small group of people with normal cell secretion protein is more, also known as the background value is high, this is also possible, but this This is also possible, but this situation is only slightly higher than the normal value and remains at a level for a long time. Therefore, if the glycoconjugate antigen 72-4 is high, it is not equal to gastric cancer or intestinal cancer.
