This method is intended to be used as an aid in the management of ovarian cancer patients with metastatic disease by monitoring the progression of regression of disease in response to treatment. The Abbott ARCHITECT CA125 II assay is not intended for screening or diagnosis of ovarian cancer.
Results may be affected if patient has developed heterophillic antibodies due to exposure to animal based protein products.
A high dose hook effect is not seen up to 180,000 U/mL.
The Abbot ARCHITECT CA125 II method is used. Results obtained with different assay methods or kits cannot be used interchangeably.
