Liver Kidney Microsomal Antibodies (LKM)
The Liver Kidney Microsomal (LKM) Antibodies blood test detects autoantibodies directed against enzymes found in liver and kidney cells. These antibodies are most commonly associated with autoimmune liver disease, particularly autoimmune hepatitis. Autoimmune hepatitis occurs when the immune system mistakenly attacks healthy liver tissue, leading to inflammation and potential liver damage. Symptoms may include fatigue, jaundice, abdominal discomfort, joint pain, or abnormal liver function tests. LKM antibodies are most frequently associated with type 2 autoimmune hepatitis, which is more commonly seen in children and young adults, but can occur at any age. This test is usually requested when liver enzymes are persistently elevated or when autoimmune liver disease is suspected. Results are interpreted alongside other autoantibody tests, liver function tests, imaging, and clinical findings.
