The CA 19-9 Test is a blood test that measures the level of cancer antigen 19-9 (CA 19-9), a protein that is often elevated in the blood of individuals with pancreatic cancer and other gastrointestinal cancers. It is mainly used for monitoring cancer progression and treatment response rather than for diagnosis.
Why is the CA 19-9 Test Done?
✅ Monitor pancreatic cancer – Helps track cancer progression and response to treatment.
✅ Detect cancer recurrence – Used after treatment to check if cancer has returned.
✅ Assess gastrointestinal cancers – Can be elevated in stomach, bile duct, and colorectal cancers.
✅ Differentiate between benign and malignant conditions – Can help doctors in diagnosis.
