Detection of antibodies aids in the diagnosis of autoimmune liver diseases such as autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC)
The ASMA (Actin (Smooth Muscle) Antibody) blood test is used to detect the presence of smooth muscle antibodies in the blood and aid in the diagnosis of autoimmune hepatitis. This test is useful in determining whether liver inflammation is caused by an autoimmune condition or another cause. Smooth muscle antibodies are proteins produced by the immune system that attack structural proteins in smooth muscle, potentially impacting the liver and other tissues. The ASMA test can help in the differentiation of autoimmune liver damage from other causes.
