Some common liver function tests include: 1  Alanine transaminase (ALT). ALT is an enzyme found in the liver that helps your body metabolize protein. 2  Aspartate transaminase (AST). AST is an enzyme that helps metabolize alanine, an amino acid. 3  Alkaline phosphatase (ALP). ALP is an enzyme in the liver, bile ducts and bone.  Albumin and total protein. It is released into the blood when cells that contain it are damaged. A liver function test, ALT is more sensitive for the detection of hepatocyte injury than for biliary obstruction. ALT is more specific for liver injury than AST (SGOT). Useful for hepatic cirrhosis, other liver disease. Alanine Aminotransferase (ALT) (SGPT) (GPT) (Liver Function) Blood Test. The ALT level is tested to look for and evaluate damage to the liver. This test measures the amount of an enzyme called glutamate pyruvate transaminase (GPT) in your blood. This enzyme is found in many body tissues in small amounts, but it is very concentrated in the liver. By Mayo Clinic Staff. Elevated liver enzymes may indicate inflammation or damage to cells in the liver. Inflamed or injured liver cells leak higher than normal amounts of certain chemicals, including liver enzymes, into the bloodstream, which can result in elevated liver enzymes on blood tests. The specific elevated liver enzymes most commonly found are: Alanine transaminase (ALT) Aspartate transaminase (AST) The liver enzyme test results are typically used together, not individually, to diagnose a liver problem. 1  If the tests indicate a problem, a liver biopsy may be necessary to confirm the test results. 2  Some prescription and over-the-counter medications can cause an increase in ALT levels. The liver enzyme test results are typically used together, not individually, to diagnose a liver problem. 1  If the tests indicate a problem, a liver biopsy may be necessary to confirm the test results. Results can be elevated by many prescription medications and some over the counter drugs and supplements. •The liver uses enzymes and proteins synthesize proteins. •(an excess of two of these enzymes, aspartate aminotransferase. (AST) and alanine aminotransferase (ALT) are elevated in serum. when liver cells have been damaged) •The liver also inactivates hormones and regulates the. amount of testosterone and estrogen in the blood. •The liver plays a major role in break down and synthesis. of cholesterol. Liver function tests (LFTs or LFs) are groups of blood tests that give information about the state of a patient's liver. These tests include prothrombin time (PT/INR), aPTT, albumin, bilirubin (direct and indirect), and others. Liver transaminases (AST or SGOT and ALT or SGPT) are useful biomarkers of liver injury in a patient with some degree of intact liver function. Most liver diseases cause only mild symptoms initially, but these diseases must be detected early. Hepatic (liver) involvement in some diseases can be of crucial importance. Liver function tests check the levels of certain enzymes and proteins in your blood. Levels that are higher or lower than normal can indicate liver problems. Some common liver function tests include: Alanine transaminase (ALT). ALT is an enzyme found in the liver that helps your body metabolize protein. When the liver is damaged, ALT is released into the bloodstream and levels increase. Aspartate transaminase (AST). Liver Enzyme and Function Blood Test Results. Liver enzymes, or liver (hepatic) function tests, are common blood tests used to determine if the liver is functioning normally or if it has an injury or disease.
