How is the CA-125 blood test given and what may the results mean?

The test involves taking a small sample of the patient’s blood for testing. Patients do not need to fast for this test.

Many things other than ovarian cancer can lead to a person having a “positive” test score. These can include a woman having fibroids in the uterus or if she is currently menstruating. Sometimes people will have a high score but may have other types of cancer, such as endometrial, peritoneal, and fallopian tube cancers.

If your doctor thinks you may have ovarian cancer, or thinks you are at increased risk of developing it, a CA-125 test would be just one piece of the approach to monitoring your condition.
