There is no fixed standard for the normal reference range of glycoconjugate antigen CA242, because different testing institutions apply different kits, the reference range of the test also varies greatly, commonly <20IU/mL, or <10IU/mL is the normal value, the specific situation should be combined with the actual test results, further analysis and judgment.
CA242 as a common indicator of digestive system tumors, abnormalities can be seen in pancreatic cancer, biliary tract cancer, gastric cancer, intestinal cancer and other diseases. If patients are found to have abnormally elevated glycoconjugate antigen CA242, the possibility of tumors needs to be considered clinically, and patients should also combine with imaging examinations of the whole body, such as CT, ultrasound, etc. for further judgment. In addition, patients with benign diseases, such as severe infections, may also have elevated tumor markers, including glycoprotein CA242. If patients have abnormally elevated glycoprotein CA242, they need to rule out tumors in combination with imaging, and then diagnose whether it is an infectious disease in combination with systemic symptoms.
Patients with autoimmune diseases, such as rheumatoid arthritis and lupus erythematosus, may also have elevated tumor markers in their bodies when the disease is in an active state.
