Your doctor may order this test if you have signs of certain diseases (such as hepatitis and cirrhosis) that can trigger the body to form antibodies against smooth muscle.
Normally, there are no antibodies present. (Negative Test)
A positive test may be due to:
Chronic active hepatitis
Cirrhosis
Infectious mononucleosis
The test also helps distinguish autoimmune hepatitis from systemic lupus erythematosus
