CA 125 test for ovarian cancer

What is a CA 125 test?

Your doctor will perform this blood test to measure the level of a protein called CA-125 in the blood. High amounts of CA-125 may indicate ovarian cancer, as well as less serious conditions, such as endometriosis or inflammation in the abdomen. We combine this test with other screening methods.

CA 125 test for ovarian cancer

We continue to measure CA-125 levels during treatment to monitor how you are responding. If test results show that protein levels in the blood are rising, we will perform further testing and change your treatment plan if needed.
