AMA (Anti-Mitochondrial Antibodies)
AMA is the key serological marker for primary biliary cholangitis. Including it in an autoimmune screen enables early detection and timely treatment initiation.
What It Measures
This test detects and quantifies anti-mitochondrial antibodies in your blood. A positive result, particularly the M2 subtype, is highly specific for primary biliary cholangitis.
Why It Matters
AMA positivity with elevated alkaline phosphatase is sufficient for PBC diagnosis in most cases, often without the need for liver biopsy. Early detection enables treatment to slow disease progression.
When to Test
Testing could be indicated when PBC is suspected: unexplained cholestatic liver enzyme elevation, chronic fatigue with pruritus, or as part of autoimmune liver disease evaluation.

Lifestyle Tips
If AMA-positive, consult a hepatologist for further evaluation. Avoid alcohol to protect liver function. Ursodeoxycholic acid (UDCA) is the standard treatment for PBC and can significantly slow disease progression when started early.
