Elevated transaminases Elevated transaminases. In medicine, the presence of elevated transaminases, commonly the transaminases alanine transaminase (ALT) and aspartate transaminase (AST), may be an indicator of liver damage. Other terms employed include transaminasemia and transaminitis, although some sources consider the latter pathologically meaningless.

High AST When AST is elevated more than ALT, this commonly shows that the cause of the liver condition is alcohol-related. If ALT is elevated more than AST, this shows the presence of liver disease but suggests a non-alcoholic cause for the affliction. Alcohol abuse is the single most common cause of liver disease.

Aspartate Aminotransferase (AST)  [en EspaÃ±ol] Aspartate Aminotransferase (AST) An aspartate aminotransferase (AST) test measures the amount of this enzyme in the blood. AST is normally found in red blood cells, liver, heart, muscle tissue, pancreas, and kidneys. AST formerly was called serum glutamic oxaloacetic transaminase (SGOT). Low levels of AST are normally found in the blood. When body tissue or an organ such as the heart or liver is diseased or damaged, additional AST is released into the bloodstream. The amount of AST in the blood is directly related to the extent of the tissue damage. After severe damage, AST levels rise in 6 to 10 hours and remain high for about 4 days. The AST test may be done at the same time as a test for alanine aminotransferase, or ALT.

- If the blood work indicates another cause for the elevated AST levels than liver disease, tests for heart problems, kidney functioning, and other diagnostic procedures related to the various non-liver causes of high AST are indicated.

Liver Blood Tests Normal levels of AST and ALT may slightly vary depending on the individual laboratory's reference values. Typically the range for normal AST is reported between 10 to 40 units per liter and ALT between 7 to 56 units per liter. Mild elevations are generally considered to be 2-3 times higher than the normal range.

- Why It Is Done. An aspartate aminotransferase (AST) test is done to: 1  Check for liver damage. 2  Help identify liver disease, especially hepatitis and cirrhosis. 3  Liver disease may produce symptoms such as pain in the upper abdomen, nausea, vomiting, and sometimes jaundice. 4  Check on the success of treatment for liver disease.

What Causes Elevated AST Levels? Quick Answer. Causes of elevated aspartate aminotransferase, or AST, levels include a heart attack; liver, kidney or lung damage; medicines; high doses of vitamin A; and mononucleosis, states WebMD. Normal levels for adult women and men range between 10 and 36 units per liter and 14 and 20 units per liter respectively. Keep Learning.

AST Levels Normal serum AST is 14-20 IU per liter in men and 10-36 IU per liter in women. When a blood test for AST indicates elevation above normal range, the indication is that damage may be present to one of the organs where AST is normally found.

What do elevated AST and ALT liver enzymes mean? It is important to clarify that ALT and AST levels do not reflect the function of the liver, even though they commonly are referred to as liver function tests or LFTs. They only are used to detect inflammation due to injury or damage to the liver from any source. Even in conditions when AST and ALT are very elevated, the liver may function properly.

The AST/ALT Story Levels of AST may also be markedly elevated (often over 100 times normal) as a result of exposure to drugs or other substances that are toxic to the liver as well as in conditions that cause decreased blood flow (ischemia) to the liver.ery high levels of AST (more than 10 times normal) are usually due to acute hepatitis, sometimes due to a viral infection. With acute hepatitis, AST levels usually stay high for about 1-2 months but can take as long as 3-6 months to return to normal.

What Does High AST (SGOT) and ALT (SGPT) Mean? High aspartate aminotransferase and alanine aminotransferase counts may indicate liver damage, including disease, according to WebMD. The extent of liver tissue damage is directly related to the amount of AST and ALT in the blood. The higher the count, the more likely the liver is damaged or diseased. Continue Reading.

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.

Elevated transaminases In medicine, the presence of elevated transaminases, commonly the transaminases alanine transaminase (ALT) and aspartate transaminase (AST), may be an indicator of liver damage.

- Elevated al-kaline phosphatase and aminotransferases can indicate a mixed pattern of injury. High AST, ALT suggest liver cell damage Both aspartate aminotransferase (AST) and ALT are normally present in serum at low lev-els, usually less than 30 to 40 U/L. Although the actual values may differ from laboratory to laboratory, normal serum levels are usually less than 40 U/L for AST and less than 50 U/L for ALT.

- Definition. 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: 1  Alanine transaminase (ALT).2  Aspartate transaminase (AST).nflamed 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.

- AST (SGOT) and ALT (SGPT) are sensitive indicators of liver damage or injury from different types of diseases. But it must be emphasized that higher-than-normal levels of these liver enzymes should not be automatically equated with liver disease. They may mean liver problems or they may not.

- What Abnormal Results Mean. An increased AST level is usually a sign of liver disease. Liver disease is even more likely when the levels of substances checked by other liver blood tests have also increased. Pregnancy and exercise may also cause an increased AST level.

Liver function tests An increase in AST levels may indicate liver damage or disease or muscle damage. Alkaline phosphatase (ALP). ALP is an enzyme in the liver, bile ducts and bone. Higher-than-normal levels of ALP may indicate liver damage or disease, such as a blocked bile duct, or certain bone diseases.

Aspartate Aminotransferase Damage to these organs or hemolysis releases the enzyme, resulting in elevated AST levels in the serum. Serum levels generally parallel the extent of damage. Another enzyme, alanine aminotransferase or ALT, is primarily found in the liver. AST and ALT are often measured together as part of a liver function panel to detect liver damage. Liver diseases in which AST is higher than ALT include alcohol-induced liver damage, cirrhosis, and liver tumors.

What does AST on a blood test mean? AST stands for aspartate transaminase. It is an enzyme found in various cells, including liver cells, and elevated levels may indicate liver damage, but must be interpreted in the context of other liver tests, as it is not only found in liver cells, but other cell types as well.t is an enzyme found in various cells, including liver cells, and elevated levels may indicate liver damage, but must be interpreted in the context of other liver tests, as it is not only found in liver cells, but other cell types as well.
