About Liver kidney microsomal antibodies

What are liver-kidney microsomal antibodies?

Liver-kidney microsomal (LKM) antibodies associated with autoimmune hepatitis. Antibodies are proteins typically produced by the immune system to target and protect against harmful entities. In some cases, the immune system can malfunction, producing antibodies which target and attack the body’s own cells. LKM-1 antibodies target an enzyme in the liver causing inflammation.

Over time this inflammation can cause scarring of the liver resulting in cirrhosis. Autoimmune hepatitis is most common in females and can be divided into type 1 and type 2. More people are affected by type 1 autoimmune hepatitis in which smooth muscle antibodies (SMA) or anti-nuclear antibodies might be present.

Whilst rarer, type 2 is more severe and is indicated by the presence of LKM antibodies. Symptoms include yellowing of the skin (jaundice), itching, loss of appetite, nausea and vomiting, fatigue, joint and muscle pain and rashes.

Why take the test?

This test measures the level of LKM antibodies in the blood and can be used to help diagnose autoimmune hepatitis and distinguish between type 1 and type 2.
