Description:
The presence of LKM-1 antibodies can be used in conjunction with clinical findings and other laboratory tests to aid in the diagnosis of autoimmune liver diseases such as autoimmune hepatitis (AIH-2). The liver kidney microsome type 1 antibody (anti-LKM-1 or CYP2D6 antibody) test is primarily used along with a smooth muscle antibody (SMA) and an antinuclear antibodies (ANA) test to help diagnose autoimmune hepatitis and to differentiate between the two major types, type 1 and type 2.
