Use:  The presence of mitochondrial antibodies can be used in conjunction with clinical findings and other laboratory tests to aid in the diagnosis of primary biliary cirrhosis (PBC).

Limitations:  The presence of immune complexes in the patient's sample may cause an increased level of nonspecific binding and produce false-positive results. Not all PBC patients are positive for mitochondrial antibodies. Results of this assay should be used in conjunction with clinical findings and other serologic tests.
