CA 242

The CA 242 test measures the level of the carbohydrate antigen CA 242 in blood, a tumor marker most commonly associated with gastrointestinal malignancies such as colorectal and pancreatic cancers. Performed by quantitative immunoassay on a serum sample, CA 242 is used primarily to monitor disease activity, assess response to therapy, and detect early recurrence rather than as a sole diagnostic tool. This service provides Dubai-licensed home blood collection and fast, certified laboratory results that can be shared with your treating physician for timely clinical decisions.
