What is the Alanine Aminotransferase Test (ALT)
An Alanine transaminase (ALT) or serum Glutamic-pyruvic transaminase (SGPT) or alanine aminotransferase (ALAT) blood test will measure the amount of enzymes that are in your blood. This test takes place most commonly in the liver and in a part of the kidney, cardiovascular system, muscles as well as pancreas. This test is often ordered in conjunction with a liver panel or liver function test to acknowledge whether or not the liver is diseased or damaged. Low levels are found in the blood but when the liver gets damaged then the test result number will increase. The higher the number the more damaged the liver is, and this test is most often done with other tests, such as the aspartate aminotransferase or aspartate transaminase (AST) test.
