- What are liver tests? Liver tests (LTs) are blood tests used to assess the general state of the liver or biliary system. Few of these tests actually measure how well the liver or biliary system is functioning, but rather reflect the presence of damage or inflammation.

Liver Panel The liver panel test involves several tests that check how well your liver is working. These tests are called liver function tests. They are blood tests. Several different enzymes (proteins) made by the liver are measured in the blood: SGOT (serum glutamic oxaloacetic transaminase), also called AST (aspartate aminotransferase)

Normal Levels for Liver Enzymes Liver enzyme blood tests are often performed as part of a more comprehensive test called a liver function test. The reason for this is because liver enzyme results only tell part of the story related to liver health and condition. Liver enzyme results measure enzymes the organ produces in response to damage or disease. Other testing also involved in the liver function test measures actual liver activity.

Additional Tests You Might Need Liver enzyme tests, formerly called liver function tests (LFTs), are a group of blood tests that detect inflammation and damage to the liver. They can also check how well the liver is working.he cells in the liver contain proteins called enzymes that drive these chemical reactions. When liver cells are damaged or destroyed, the enzymes in the cells leak out into the blood, where they can be measured by blood tests.

Abnormal Liver Function Tests Most tests measure hepatocellular damage rather than function, so they are rather misnamed. True liver function tests (LFTs) are those that measure synthesis of proteins made by the liver (albumin, clotting factors) or the liver's capacity to metabolise drugs. LFTs are not specific to specific systems or disease processes, yet abnormalities may indicate significant or serious disease.

- Other blood tests pertaining to the liver are measurements of some of the other enzymes found the liver. In addition to AST and ALT, alkaline phosphatase, 5' nucleotidase, and gamma-glutamyl transpeptidase (GGT) are a few of the other enzymes located in the liver.

Liver function tests 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).

List of Gallbladder Function Tests Liver Enzymes: In regards to liver function tests, the levels of three main enzymes are checked. The first enzyme is alanine transaminase (ALT). It is used in protein digestion and its blood level can rise in abnormal gallbladder function after inflammation or injury.

- These tests are drawn from a vein in a doctor’s office, or if you are hospitalized and a special IV is available it can be drawn from that line without a needle stick. The liver enzyme test results are typically used together, not individually, to diagnose a liver problem.

- Blood enzyme tests. Enzymes are chemicals which help to regulate a number of chemical reactions, and that take place in the body. Blood enzyme tests can be used to measure the levels and activity of certain enzymes. Some blood enzyme tests assess the liver enzymes and others test for damage to the heart. Creatine kinase. Creatine kinase is an enzyme which is produced by the majority of muscle cells.

- Other enzymes that may be included in a liver function test are alkaline phosphatase, or AP, gamma-glutamyltranferase, or GGT, lactate dehydrogenase, or LDH, and 5-nucleotidase. Many prescription medications may cause an elevation in liver enzymes and some lead to severe liver injury if not discontinued.

Abnormal Liver Function Tests What are liver function tests? A liver function test (LFT) is a blood test that gives an indication of whether the liver is functioning properly. The test is also very useful to see if there is active damage in the liver (hepatitis) or sluggish bile flow (cholestasis). Liver function tests measure the amount of particular chemicals in the blood. This gives a gauge of possible damage to liver cells — damage that can be caused by many things including HCV.

HIV and Liver Function Tests Updated June 29, 2016. Liver function tests (LFTs) are a battery of routine blood tests that gives your doctor an idea of how well your liver is working. From these investigations, your doctor can identify underlying liver dysfunction, medication stresses affecting the liver, or diseases of the liver such as hepatitis B (HBV) or hepatitis C (HCV).

Using Liver Enzymes AST and ALT to Diagnose Liver Damage and Disease Liver enzymes allow doctors to learn about the health of your liver. There are thousands of these enzymes in the liver and blood stream, but two of them -- known as aminotransferases AST and ALT -- are especially useful for determining liver disease.

- Guide. An alanine aminotransferase (ALT) test measures the amount of this enzyme in the blood. ALT is found mainly in the liver, but also in smaller amounts in the kidneys, heart, muscles, and pancreas.ALT was formerly called serum glutamic pyruvic transaminase (SGPT).he ALT test is often done along with other tests that check for liver damage, including aspartate aminotransferase (AST), alkaline phosphatase, lactate dehydrogenase (LDH), and bilirubin. Both ALT and AST levels are reliable tests for liver damage.

Liver function tests Liver function tests. Liver function tests may be arranged to help diagnose or monitor liver problems. These blood tests may also be called LFTs, liver panel or hepatic function tests. The liver's job is to filter blood as it travels around the body, but it can become damaged or affected by disease.

- Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) are three enzymes that are present inside the cells of the liver. When the cells of the liver are damaged, the enzymes are measured in higher concentrations in the blood.ther Tests. Other tests performed during a liver function test may include gamma glutamyl transferase (GGT) and cholesterol. GGT is also found in the liver cells and is found in higher blood concentrations when the bile ducts are blocked.

Additionally, in conjunction with the aspartate aminotransferase test (AST), it helps to distinguish between heart damage and liver tissue damage.

Liver Function Tests Liver function tests are blood tests that check to see how well your liver is working. They check for liver damage, and can help diagnose liver diseases such as hepatitis and cirrhosis. You may have liver function tests as part of a regular checkup. Or you may have them if you have symptoms of liver disease. Doctors also use the tests to monitor some liver diseases, treatments, and possible side effects of medicines. Liver function tests measure certain proteins, enzymes, and substances, including: Albumin, a protein that the liver makes.
