What is a CA-125 Test?

The CA-125 test is a blood test that measures the amount of cancer antigen 125 (CA-125) in the blood. CA-125 is a protein that is often found in higher levels in individuals with certain types of cancer, particularly ovarian cancer. However, elevated levels of CA-125 do not exclusively indicate cancer and can be influenced by a variety of medical conditions.

Why is the CA-125 Test Used?

The primary use of the CA-125 test is as a tumour marker to assess the presence of ovarian cancer. It can be used to evaluate treatment efficacy, monitor for cancer recurrence, and in some instances, as part of the diagnostic process for ovarian cancer. In addition to ovarian cancer, other conditions that might lead to elevated CA-125 levels include menstruation, pregnancy, endometriosis, pelvic inflammatory disease, and liver diseases.

Who Should Consider the Test?

The CA-125 test may be recommended for individuals who are at high risk of ovarian cancer, such as those with a family history of the disease or certain genetic mutations like BRCA1 or BRCA2. It is also used to monitor patients who have already been diagnosed with ovarian cancer to check how they are responding to treatment. However, it is not typically used for general screening in women without symptoms or significant risk factors, as elevated CA-125 levels can be caused by non-cancerous conditions as well.

How is the Test Performed?

The CA-125 test is a simple blood test. A healthcare provider will draw a small sample of blood from a vein, usually in the arm. This sample is then sent to a laboratory where it is analyzed for the level of CA-125. The results are usually available within a few days. Depending on the laboratory, the reference range for normal CA-125 levels may vary, but typically it is considered to be below 35 U/mL.

Interpreting the Results

An elevated CA-125 level can suggest the presence of ovarian cancer or other conditions but is not conclusive on its own. It should be interpreted in conjunction with other diagnostic tests and the individual’s medical history. If ovarian cancer is suspected, further diagnostic imaging and possible biopsy may be warranted to make a definitive diagnosis. Conversely, normal CA-125 levels do not entirely rule out ovarian cancer, as some individuals with the disease may not have elevated CA-125.

Conclusion

The CA-125 test is a useful tool in specific clinical settings, particularly for monitoring patients already diagnosed with ovarian cancer. It is not a standalone diagnostic tool but rather part of a broader diagnostic and monitoring strategy. Anyone considering the CA-125 test should discuss its potential benefits and limitations with their healthcare provider.

What is a CA-125 Test?

The CA-125 test is a blood test. It checks how much of a protein called CA-125 is in the blood. This protein can be higher when someone has certain types of cancer, like ovarian cancer. But, having more CA-125 doesn't always mean a person has cancer. Other health problems can also raise CA-125 levels.

Why is the CA-125 Test Used?

Doctors use the CA-125 test to look for ovarian cancer. It helps them see if treatment is working and to watch for cancer coming back. The test can also help find other conditions like menstruation, pregnancy, endometriosis, pelvic inflammatory disease, and liver problems.

Who Should Consider the Test?

People who might need the test include those with a high risk of ovarian cancer, like those with a family history or certain genetic changes (BRCA1 or BRCA2). It is also used for people already diagnosed with ovarian cancer to see how treatment is going. The test is not usually given to women with no symptoms or no risk factors because other things can cause high CA-125 levels.

How is the Test Performed?

The CA-125 test is a simple blood test. A healthcare worker will take a small amount of blood from a vein, often in the arm. The blood goes to a lab to check the CA-125 level. You usually get the results in a few days. Normal CA-125 levels are usually below 35 U/mL, but this can vary by lab.

Interpreting the Results

If the CA-125 level is high, it might mean ovarian cancer or another health issue, but it is not sure by itself. Doctors use other tests and your health history to figure out what is going on. If doctors think you might have ovarian cancer, they might do more tests, like scans or a biopsy. Even normal CA-125 levels do not always mean there is no cancer, because some people with cancer have normal levels.

Conclusion

The CA-125 test is helpful for people with ovarian cancer and during treatment. It is one part of the larger picture for diagnosing and checking on cancer. Talk to your doctor about whether this test is right for you and the good and bad points of having it.
