AST or Aspartate Aminotransferase is a type of enzyme usually found in red blood cells, heart, pancreas, muscle tissues but is mostly made in the liver. Every laboratory has its own normal range, however, so certain results that fall outside of these reported norms may still be considered a “normal” result by some medical providers. His write-ups aim at educating people not by just giving facts but by infusing human touch. AST is short for aspartate aminotransferase is also called SGOT (Serum Glutamic-Oxaloacetic Transaminase) or GOT (Glutamic-Oxaloacetic Transaminase), which is an enzyme found throughout your body but mostly in your heart and liver and to a lesser extent, in the kidneys and muscles. Normal results vary from laboratory to laboratory and might be slightly different for women and children. AST often varies between normal and slightly increased with chronic hepatitis, so the test may be ordered frequently to determine the pattern. Normal results vary from laboratory to laboratory and might be slightly different for women and children. Other liver functions concern protein metabolism. Your liver is involved in many important functions in the body. However, the ranges of AST and ALT numbers may differ slightly depending on the technique and protocols used by different laboratories worldwide. This result is typical for adult men. Personal hygiene items are never to be shared, Maintain hand hygiene especially while preparing or eating food. Such moderate increases may also be seen in other diseases of the liver, especially when the bile ducts are blocked, or with cirrhosis or certain cancers of the liver. Fat-splitting enzymes (lipases) can then digest the fat molecules more effectively. However, all the labs provide the reference normal range of values available on the report. This action, called emulsification, greatly increases the total surface area of the fatty substance. AST blood test normal range: Normal AST is less than 42U/L [units per liter] (range 8 to 48 U/L). Progesterone Levels Chart- High, Low, And Normal Range. What is the magnitude of AST and ALT elevations for acute viral hepatitis? If AST levels increase, then the person may be switched to another medication. Usually, the AST levels in the bloodstream are low. Values are typically at least 10 times above the normal range. AST was earlier called as Serum Glutamic Oxaloacetic Transaminase or simply SGOT. In hemolytic jaundice red blood cells are destroyed too rapidly, as happens with an incompatible blood transfusion or a blood infection. Jaundice, a yellowing of the skin and mucous membranes due to accumulation of bile pigment, has several causes. Normally bile does not enter the duodenum until cholecystokinin stimulates the gallbladder to contract. Detoxifies many poisons and drugs in the blood. A high value of the AST test is when the units per liter of serum value are higher than the normal range. This result is typical for adult men. AST and ALT (alanine aminotransferase) are considered to be two of the most important tests to detect liver injury, although ALT (alanine aminotransferase) is more specific for the liver than is AST and is more commonly increased than is AST. It may also be done during the treatment to understand the effectiveness of the treatment. The use of this ratio was first suggested by de Ritis in 1955. 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. Sometimes AST is compared directly to ALT and an AST/ALT ratio is calculated. However, this range may vary depending on the type of technique and protocols used by the lab. An AST test is often performed along with an alanine aminotransferase (ALT) test. The high end of the reference range is referred to as the upper limit of normal (ULN). Indications. Normal AST is less than 42U/L [units per liter] (range 8 to 48 U/L). It breaks down alcohol, drugs, and toxic wastes in the blood, which then pass from the body through urine and stool. What Is Blood Differential Test And What Does Abnormal Results Mean? However, this test is ordered to be done if the person shows any symptoms of a liver problem. Picks up glucose from nutrient-rich blood returning from the alimentary canal and stores this carbohydrate as glycogen for subsequent use by the body.
