Description

The CEA test measures the level of carcinoembryonic antigen (CEA) in your blood, a protein that can be produced by cancer cells or by normal cells in response to cancer. CEA is considered a tumor marker and can provide information about cancer progression and treatment response.

Why the CEA Test Is Important

The CEA test is primarily used to:

  • Learn more about a cancer after diagnosis
  • Monitor how well cancer treatment is working
  • Detect if cancer has returned after treatment

When to Get a CEA Test

  • Not for Screening: This test is not used to diagnose or screen for cancer.
  • It is only recommended for individuals who have already been diagnosed with cancer.

Understanding CEA Levels

  • High CEA Levels: May indicate the presence of cancer or poorer prognosis, but can also be influenced by non-cancerous conditions.
  • Changes Over Time: Tracking CEA levels over time can help determine treatment effectiveness or indicate cancer recurrence.

Fasting: Not required.
