Test
Limitations:

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.
