CEA (Carcinoembryonic Antigen) Pretreatment Lab Value


**Note 1:** Physician statement of CEA (Carcinoembryonic Antigen) Pretreatment Lab Value can be used to code this data item when no other information is available. **Note 2:** Record the lab value of the highest CEA test result documented in the medical record **prior to treatment or polypectomy**. The lab value may be recorded in a lab report, history and physical, or clinical statement in the pathology report. **Note 3:** CEA is a tumor marker that has value in the management of certain malignancies. **Note 4:** Record to the nearest tenth in nanograms/milliliter (ng/ml) the highest CEA lab value documented in the medical record **prior to treatment or polypectomy.** * ***Example:*** Code a pretreatment CEA of 7 ng/ml as 7.0. **Note 5:** For an uncertain value, record the stated closest value. * ***Example:*** Code a value stated as "less than 0.5 ng/ml" as 0.5. **Note 6:** Record 0.1 when the lab results are stated as less than 0.1 ng/ml with no exact value. **Note 7:** The same laboratory test should be used to record information in CEA Pretreatment Interpretation [NAACCR Data Item #3819].
