Limitations
Patients with Heterophile antibodies (HAMA) may exhibit falsely elevated or falsely depressed results.
CA 125 results should not be used interchangeably with other manufacturers’ methods for CA 125 determinations. Consistent tube type should be used to collect serial specimens.
CA 125 levels are not useful in screening the general population for cancer.
CA 125 levels should not be used alone as absolute evidence of the presence or absence of malignant disease. Clinical evaluation and other diagnostic procedures are needed.
