Patients with gastrointestinal tumors such as pancreatic, liver, gastric, colorectal tumors and some other malignancies have been shown to have elevated serum CA 19-9 levels. Serum CA 19-9 levels may be useful for monitoring disease activity or predicting relapse following treatment.
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your CA 19 - 9. Your doctor will give specific instructions depending on your condition on how to prepare for CA 19 - 9.
