As with all tests containing monoclonal antibodies, erroneous findings may be obtained from samples taken from patients who have been treated with monoclonal mouse antibodies (e.g., OC 125) or who have received them for diagnostic purposes. In rare cases, interference due to extremely high titers of antibodies to ruthenium can occur. Elecsys CA125 II contains additives which minimize these effects. Extremely high titers of antibodies to streptavidin can occur in isolated cases and cause interference. For diagnostic purposes, the Elecsys CA125 II finding should always be assessed in conjunction with the patient's medical history, clinical examination and other findings.

Hemolysis: No significant interference up to an H index of 3200 (approximate hemoglobin concentration: 3200 mg/dL).

Lipemia: No significant interference up to an L index of 2000 (approximate triglycerides concentration: 4000 mg/dL). Note there is poor correlation between turbidity and triglyceride concentration.

Icterus: No significant interference up to an I index of 66 (approximate conjugated and unconjugated bilirubin concentration: 66 mg/dL).
