A CA 27-29 blood test measures the amount of CA 27-29 antigen in your blood.
Understanding CA 27-29
What is CA 27-29?
CA 27-29 is an antigen, a substance that can trigger your body's immune system. Certain cancer cells release this antigen into the bloodstream. Therefore, measuring the level of CA 27-29 in the blood can provide important information about the presence and activity of cancer cells. As such, CA 27-29 acts as a tumor marker.
What Does the CA 27-29 Test Do?
The CA 27-29 blood test specifically measures how much of this particular antigen is present in the blood. Elevated levels of CA 27-29 may indicate the presence of certain cancers, particularly breast cancer.
Why is This Test Important?
- Monitoring Treatment: If you have been diagnosed with cancer, the CA 27-29 test can help to monitor the effectiveness of treatment.
- Detecting Recurrence: This test can also be used to monitor for any potential recurrence of cancer after treatment.
- Aiding Diagnosis: While not used for primary diagnosis, the test can aid in the diagnostic process when cancer is suspected.
How Does the Test Work?
The test involves a simple blood draw, which is then sent to a laboratory for analysis. The lab measures the level of CA 27-29 in your blood. High levels may require further evaluation and diagnostic tests.
Key Points About CA 27-29 Testing
| Feature | Description |
|---|---|
| What it is | Measures CA 27-29 antigen in blood; acts as tumor marker. |
| Antigen | Substance that stimulates the immune system, released by some cancer cells. |
| Purpose | Aids in monitoring treatment effectiveness and detecting cancer recurrence, specifically breast cancer. |
| Sample | Blood sample |
In Summary
The CA 27-29 blood test is a valuable tool in cancer management, primarily for monitoring cancer activity. While not a standalone diagnostic test, it plays a critical role in the follow-up and management of cancer, mainly breast cancer. It measures the amount of CA 27-29 antigen, a tumor marker, in the blood, helping to monitor treatment and detect recurrences.
