Patient care diagnostic tools, tests, procedures
Liver function tests: Tests that monitor liver function are usually performed by withdrawing a sample of blood.
Autoimmune liver disease panel: A series of tests performed when autoimmune liver disease is suspected. These tests include anti-smooth muscle antibodies, anti-mitochondrial antibodies, anti-nuclear antibodies, and serum protein electrophoresis.
How the tests are performed: Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and a tourniquet (an elastic band) or blood pressure cuff is placed around the upper arm to apply pressure and restrict blood flow through the vein. This causes veins below the tourniquet to distend (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 tourniquet 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.
