## Why This Test Is Done


Your doctor may order this test if you have symptoms like itching, fatigue, or jaundice, or if they suspect an autoimmune liver disease. It’s also used to confirm or track PBC progression or response to treatment.


## What to Expect Before the Test


No special preparation is needed. A blood sample is drawn from a vein, usually in your arm. You may feel a slight pinch, but it’s quick and painless.


## What the Results Mean


Positive results suggest a high likelihood of PBC or other autoimmune liver conditions. However, false positives can occur, so results are often interpreted alongside clinical findings and other tests.


## Common Conditions Linked to Positive Results


A positive test is most strongly associated with primary biliary cholangitis (PBC), but it can also appear in other autoimmune liver diseases or rare cases of other conditions.


## Clinical interpretation


How abnormal results are interpreted and what conditions they suggest.


Clinical Significance: Autoimmune Liver Disease Detection


## Short name


Anti-Mitochondrial Antibody (AMAb)
