Antimitochondrial Antibodies (AMA)

What Are Anti-Mitochondrial Antibodies (AMA)?

Anti-mitochondrial antibodies (AMA) are a type of autoantibody that target components within the mitochondria, particularly in liver cells. These antibodies are most commonly associated with autoimmune liver disorders.

Clinical Significance of AMA Testing

AMA testing is primarily used in the diagnosis of Primary Biliary Cholangitis (PBC), previously known as primary biliary cirrhosis. This is a chronic autoimmune liver disease that slowly destroys the bile ducts within the liver, leading to liver damage over time.

AMA and Primary Biliary Cholangitis (PBC)

Over 90% of individuals diagnosed with PBC will test positive for anti-mitochondrial antibodies, making this test highly reliable for identifying the condition. Early detection through AMA testing allows for better disease management and monitoring of liver function.

Symptoms That May Require AMA Testing

Persistent fatigue

Itchy skin (pruritus)

Jaundice (yellowing of skin or eyes)

Upper right abdominal discomfort

Elevated liver enzymes in routine blood work
