Immunology profile tests
Immunology/autoimmune profile tests are tests in which your doctor looks for liver damage caused by your immune system.
They include:
SMA (smooth muscle antibody)
This is a test used to detect autoimmune diseases such as autoimmune hepatitis (AIH), which is inflammation of the liver that occurs when the immune system attacks the liver cells. A liver biopsy is usually necessary to confirm the diagnosis and stage of the disease.
LKM (liver/kidney/microsomal antibody)
This test can be positive in another type of autoimmune hepatitis.
