What is the ca-125 test for ovarian cancer?

A doctor has provided 1 answer

Measures a protein: The ca-125 test is a blood test that detects a protein in the blood that is produced by malignant ovarian cells. It is used to help determine if an ovarian cancer patient has had a relapse, or to help differentiate a cyst found by sonogram or ct. The most important point: it should never be used as a yearly screening test, and should not be requested by patients as a screening test.
