CA 125

Diagnostic Use

CA125 is a glycoprotein most commonly measured as a tumour marker in patients with ovarian cancer.

Occasionally CA125 may be measured in combination with human epididymis protein 4 (HE4) to calculate the ROMA score which is used to assess the likelihood that an adnexal mass is malignant.
