Yes, CEA (Carcinoembryonic Antigen) is a blood test.
What is a CEA Blood Test?
The CEA blood test measures the levels of carcinoembryonic antigen in your blood. CEA is a protein that is normally found in small amounts in the body. However, high levels of CEA may indicate the presence of certain types of cancer, particularly those affecting the:
- Colon
- Rectum
- Lung
- Breast
- Stomach
- Pancreas
What Does a CEA Blood Test Tell You?
A CEA blood test can be used for several purposes, including:
- Screening for cancer: While not a definitive test for cancer, a CEA blood test can help identify individuals who may be at risk for certain types of cancer.
- Monitoring cancer treatment: CEA levels can be monitored during and after cancer treatment to assess the effectiveness of the therapy.
- Detecting cancer recurrence: If CEA levels rise after cancer treatment, it may indicate that the cancer has returned.
How is a CEA Blood Test Performed?
A CEA blood test is a simple procedure that involves drawing a small sample of blood from a vein in your arm. The blood sample is then sent to a laboratory for analysis.
Important Note:
It is important to remember that a high CEA level does not always mean you have cancer. Other factors, such as inflammation or infection, can also cause elevated CEA levels. A CEA blood test should always be interpreted in conjunction with other clinical findings and diagnostic tests.
