Definition of Autoimmune liver disease panel:

An autoimmune liver disease panel is a series of tests that is done when a person is thought to have autoimmune liver disease. An autoimmune liver disease means that the body's immune system attacks the liver.

These tests include:

• Anti-liver/kidney microsomal antibodies
• Anti-mitochondrial antibodies
• Anti-nuclear antibodies
• Anti-smooth muscle antibodies

Sometimes the panel may also include other tests. Often immune protein levels in the blood are also checked.

How the test is performed:

A blood sample is needed. For information on how this is done, see: Venipuncture.

The blood sample is sent to the laboratory for testing.

How to prepare for the test:

No special preparation is needed for this test.

How the test will feel:

When the needle is inserted to draw blood, some people feel pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.

Why the test is performed:

In autoimmune disorders, cells from the immune system attack tissues or organs. These disorders are one possible cause of liver disease. The most common autoimmune liver diseases are autoimmune hepatitis and primary biliary cirrhosis.

This group of tests helps your health care provider diagnose liver disease.
