An autoimmune liver disease panel is a series of tests performed when autoimmune liver disease is suspected. 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

Occasionally, the panel may also include additional tests. Certain immune protein levels in the blood are also checked.

Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.

Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.

In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.

The blood sample is sent to the laboratory for testing.

No special preparation is necessary for this test.

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.

Autoimmune disorders, in which cells from the immune system attack tissues or organs, 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.
