CA19.9

Also known as Pancreatic Cancer Marker, Cancer Antigen-GI 
 
A CA19.9 test measures the levels of a specific protein called cancer antigen (CA19.9) in the blood. This protein is associated with certain types of cancer, most notably affecting the pancreas.

CA19.9, a glycoprotein, is an important biomarker that helps in the identification and management of specific cancers, primarily focusing on pancreatic cancer. Given the challenges in diagnosing pancreatic cancer early, CA19.9 test plays a vital role in its detection and monitoring.
