What is CEA?
A protein elevated in some cancers. Most often used to monitor colorectal cancer treatment.
CEA Reference Range
These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| age 18+ | 0.000 – 3.00 ng/mL |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
What your CEA result may mean
Can reflect colorectal cancer or other GI cancers. Smoking also raises CEA.
Educational only — not a diagnosis. Many factors can influence a single result. Discuss anything that concerns you with a healthcare provider.
