This test determines the quantity of CA 19-9 (cancer antigen 19-9) protein in the blood. The tumour marker CA 19-9 is a sort of marker. Malignancy cells and normal cells both produce tumour markers in response to cancer in the body. CA 19-9 can be found in trace levels in the blood of healthy humans. CA 19-9 levels that are too high are often a symptom of pancreatic cancer. High amounts, on the other hand, might occasionally signal other types of cancer or certain non-cancerous illnesses, such as cirrhosis and gallstones.
