Anti-Liver/Kidney Microsomal Antibody



Test Description

The presence of LKM antibodies is used in conjunction with clinical findings and
other laboratory tests to aid in the diagnosis of autoimmune liver diseases such as
autoimmune hepatitis type 2. Autoimmune hepatitis occurs primarily in women and
is associated with very high transaminase levels and elevated gamma globulins,
especially IgG. LKM antibodies are usually evaluated, along with anti-smooth muscle
antibody and antinuclear antibody.
