The Mitochondrial Antibody with Reflex to Titer test contains 1 test with 2 biomarkers.
A high Anti-Mitochondrial Antibody (AMA) titer supports the diagnosis of primary biliary cirrhosis (PBC). Low titers of AMA may be detected in other liver disorders, which include chronic active hepatitis and cryptogenic cirrhosis. Mitochondrial M2 Antibody has an even higher specificity for PBC.
If Mitochondrial Antibody Screen is positive, Mitochondrial Antibody Titer will be performed at an additional charge (CPT code(s): 86256).
