As you are an internet user, why don't you Google it? You are bound to find the answer there.
Good luck
The smooth muscle antibody test is primarily done to diagnose autoimmune hepatitis. It is always ordered along with antinuclear antibodies (ANA). Autoimmune hepatitis is an inflammation of the liver that is associated with high concentration of auto antibodies (antibodies which instead of acting against foreign invaders, attack the body's own cells), pronounced hypergammaglobulinemia, and the absence of cholestasis. Smooth Muscle Antibody (SMA) is protein which is produced by the body's immune system and is directed against its own cytoskeletal proteins of the smooth muscle. Autoimmune hepatitis can be found in anyone at any age, but mostly women are affected.
hope this helps you understand
