In brief: CA 125

Ca 125 is not a reliable test to look for ovarian cancer.
It is used in follow up of a woman with ovarian cancer or similar cancers.

In brief: Not very.

Ca 125 is touted as a screening tool for ov ca but is elevated in only 50% of those with early stage disease.
Approx 1% of normals have a high ca 125. Since ovarian cancer is relatively uncommon, the ability of a positive test to predict ca is about 3%. There is general consensus that ca 125 is not a good screening tool for average risk females. Consider ca 125 for those with high risk.
