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-smooth muscle antibodies, anti-mitochondrial antibodies, anti-liver/kidney microsomal antibodies, and anti-nuclear antibodies. Occasionally, the panel may also include additional tests. Certain immune protein levels in the blood are also checked.

Blood is drawn from a vein on the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and an elastic band is placed around the upper arm to apply pressure and restrict blood flow through the vein. This causes veins below the band to fill with blood.

A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.

For an infant or small child, the area is cleansed with antiseptic and punctured with a sharp needle or a lancet. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. Cotton or a bandage may be applied to the puncture site if there is any continued 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. This group of tests helps your health care provider in the diagnosis of liver disease.
