About this test

A blood test performed on women that measures CA-125, a protein found on the surface of some ovarian cells and released into the blood. Blood is drawn from a vein in the arm.

A raised level can point to ovarian cancer, but it also rises with benign conditions such as fibroids and endometriosis. It is mainly used as a marker, not as a stand-alone screen for women at average risk.
