What Does ALT (SGPT) Mean in a Blood Test? Quick Answer. The ALT test checks the level of alanine aminotransferase in the blood to see if the liver is healthy. Elevated levels of the enzyme could indicate damage caused by trauma or a disease process, such as cirrhosis or a strain of hepatitis, as stated by WebMD. Continue Reading.

- ALT or Alanine Aminotransferase is an enzyme present in the liver to assist in metabolizing body protein. Normal ALT level range is 10 to 40. Elevated ALT levels can be cause for concern and may indicate liver damage. While low levels of ALT in the liver may be considered to be normal, some medical conditions can also produce a low ALT result.

alanine aminotransferase test ALT levels are used to detect liver abnormalities. Since the alanine aminotransferase enzyme is also found in muscle, tests indicating elevated AST levels might also indicate muscle damage.

Common Laboratory Tests in Liver Diseases ALT test interpretation. ALT is an enzyme produced in hepatocytes, the major cell type in the liver. The level of ALT in the blood (actually enzyme activity is measured in the clinical laboratory) is increased in conditions in which liver cells are damaged or die.

- Alanine Transaminase (ALT) is an enzyme mainly found in your liver. The ALT test measures the level of ALT in your blood. Consistently high levels of ALT in your blood can be a sign of liver damage. Aspartate Transaminase (AST) is an enzyme found in large amounts in your liver and other parts of your body.

- The alanine aminotransferase (ALT) test is done to: 1  Identify liver disease, especially cirrhosis and hepatitis caused by alcohol, drugs, or viruses. 2  Help check for liver damage. 3  Find out whether jaundice was caused by a blood disorder or liver disease. 4  Keep track of the effects of medicines that can damage the liver.LT is measured to see if the liver is damaged or diseased. Low levels of ALT are normally found in the blood. But when the liver is damaged or diseased, it releases ALT into the bloodstream, which makes ALT levels go up.

Diagnostic purpose of blood test The blood test for aspartate aminotransferase (AST) is usually used to detect liver damage. It is often ordered as part of a liver panel or comprehensive metabolic panel (CMP) to screen for and/or help diagnose liver disorders.

alanine aminotransferase test The alanine aminotransferase test (ALT) can reveal liver damage. It is probably the most specific test for liver damage. However, the severity of the liver damage is not necessarily shown by the ALT test, since the amount of dead liver tissue does not correspond to higher ALT levels.

Liver Blood Tests 1 The blood tests most frequently used for liver disease are the aminotransferases (alanine aminotransferase or ALT and aspartate aminotransferase or AST). 2  Normal levels of ALT ranges from about 7-56 units/liter, and 10-40units/liters for AST. Many drugs may cause elevated AST, and ALT and some medications can cause severe damage (for example, acetaminophen [ Tylenol liver damage]). 2  Less common causes of abnormal AST and ALT levels are wide ranging (for example, toxins, and autoimmune diseases).

Summit Medical Group Web Site ALT is an enzyme made in the liver. It is released into the blood when tissues are damaged. This enzyme is also called serum glutamic-pyruvic transaminase, or SGPT. The ALT test checks for and measures damage to the liver.

Alanine Aminotransferase (ALT)  [en EspaÃ±ol] The ALT blood test measures the level of the enzyme alanine transaminase (ALT) in the blood. ALT is found primarily in the liver, but is also found in smaller amounts in the kidneys, heart, muscles, and pancreas.he ALT test was formerly called serum glutamic pyruvic transaminase (SGPT). ALT is typically measured to determine if the liver is damaged or diseased. If the liver is damaged or diseased, it will release ALT into the blood.

- The alanine aminotransferase (ALT) test is typically used to detect liver injury. It is often ordered in conjunction with aspartate aminotransferase (AST) or as part of a liver panel to screen for and/or help diagnose liver disease.ormally, levels of ALT in the blood are low. Very high levels of ALT (more than 10 times normal) are usually due to acute hepatitis, sometimes due to a viral infection. In acute hepatitis, ALT levels usually stay high for about 1-2 months but can take as long as 3-6 months to return to normal.

What Is an Alanine Aminotransferease (ALT) Test? The alanine aminotransferase (ALT) test is a blood test that checks for liver damage. Your doctor can use this test to find out if a disease, drug, or injury has damaged your liver. Your liver does a lot of important things for you: It makes a fluid called bile that helps your body digest food. It removes waste products and other toxins from your blood.

AST/ALT ratio The AST/ALT ratio is the ratio between the concentrations of the enzymes aspartate transaminase (AST) and alanine transaminase (ALT) in the blood of a human or animal. It is measured with a blood test and is sometimes useful in medical diagnosis to differentiate between causes of liver damage, or hepatotoxicity.he AST/ALT ratio is the ratio between the concentrations of the enzymes aspartate transaminase (AST) and alanine transaminase (ALT) in the blood of a human or animal.

- Transaminases are various enzymes produced by the liver. A diagnostic blood test can determine when transaminases, most commonly aspartate transaminase (AST) and alanine transaminase (ALT), are in the blood at levels above normal and healthy, i.e. are elevated.

It is often ordered in conjunction with aspartate aminotransferase (AST) as part of a liver panel or comprehensive metabolic panel (CMP) to screen for and/or help diagnose liver disease. ALT is an enzyme found mostly in the cells of the liver and kidney. When the liver is damaged, ALT is released into the blood. This makes ALT a useful test for early detection of liver damage. AST and ALT are considered to be two of the most important tests to detect liver injury, although ALT is more specific to the liver than is AST.

Both ALT and AST levels are reliable tests for liver damage.
