A good CEA test result falls within the normal reference range.
The Carcinoembryonic Antigen (CEA) test is a blood test that measures the level of a protein called CEA. While elevated levels can be associated with certain cancers, other non-cancerous conditions can also cause high levels.
Normal CEA Levels
According to the provided reference, the normal range of CEA is 0 to 2.5 ng/mL.
- Any value within this range (0 to 2.5 ng/mL) is considered a typical or 'good' result.
- Values above the normal range (greater than 2.5 ng/mL) are considered abnormal.
Understanding Abnormal CEA Levels
The reference outlines specific interpretations for elevated CEA levels:
- Any value above the normal range (greater than 2.5 ng/mL) indicates abnormal CEA levels. While often associated with cancer, this alone doesn't confirm a diagnosis.
- A value greater than 10 ng/mL may indicate the presence of chronic disease.
- Levels greater than 20 ng/mL suggest that the cancer may have spread (metastasized).
Here's a simple breakdown based on the reference:
| CEA Level (ng/mL) | Interpretation |
|---|---|
| 0 - 2.5 | Normal (Good Result) |
| > 2.5 | Abnormal, Potential Indicator |
| > 10 | May Indicate Chronic Disease |
| > 20 | May Indicate Cancer Spread |
It's important to remember that CEA levels are just one piece of information doctors use. High CEA levels can be caused by various conditions, including smoking, infections, inflammation, and non-cancerous tumors. Conversely, normal CEA levels don't rule out cancer.
Discuss your specific CEA test results with your doctor to understand what they mean in the context of your overall health.
