Mitochondria Ab

Mitochondria antibodies (anti-mitochondrial antibodies) are proteins your immune system produces that mistakenly attack mitochondria, the energy-producing structures in your cells. This test detects these antibodies in the blood. The presence of mitochondria antibodies is a hallmark of primary biliary cholangitis (PBC), a rare autoimmune liver disease where the immune system damages bile ducts. This test helps diagnose PBC and related autoimmune liver conditions, even in early stages before significant symptoms appear.
