AMA (Anti Mitochondrial Antibody) - IFA

Understanding AMA (Anti Mitochondrial Antibody) - IFA

Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease in which the immune system mistakenly attacks the bile ducts, resulting in bile buildup in the liver. This causes scarring of the liver and can even lead to liver failure. Antimicrobial antibodies (AMAs) are produced as a part of this autoimmune response and are present in up to 95% of PBC patients. The AMA (Anti Mitochondrial Antibody) - IFA test detects the presence of these AMAs, making it a highly specific marker of PBC.

What does AMA (Anti Mitochondrial Antibody) - IFA measure?

The AMA (Anti Mitochondrial Antibody) - IFA is a blood test used to detect the presence of antibodies directed against mitochondria, the energy-producing structures within cells. This test helps diagnose autoimmune liver diseases, particularly primary biliary cholangitis (PBC), distinguishing it from other liver conditions such as autoimmune hepatitis, primary sclerosing cholangitis, and viral hepatitis.
