CEA (Carcinoembryonic Antigen) Pretreatment Lab Value

Description

CEA (Carcinoembryonic Antigen) Pretreatment Lab Value records the CEA value prior to treatment. CEA is a nonspecific tumor marker that has prognostic significance for colon and rectum cancer. CEA is **1).** A protein molecule found in many different cells of the body but associated with certain tumors and with the developing fetus. **2).** CEA is used as a tumor marker especially for gastrointestinal cancers, as colorectal cancer is the most frequent cause for an increased/elevated CEA. **3).** CEA is also elevated by biliary obstruction, alcoholic hepatitis, and heavy smoking. **4).** CEA level is most frequently tested on blood serum, but it may be tested in body fluids and/or biopsy tissue. **5).** An abnormally high CEA level prior to tumor resection is expected to fall following successful removal of the cancer. **6).** An increasing value indicates possible recurrence. There are 2 related data items that record information on CEA for Colon and Rectum. * 3820: CEA Pretreatment Lab Value * 3819: CEA Pretreatment Interpretation
