Glutamine aminotransferase 44 is a mild elevation, which is usually not very serious if caused by physiological factors, and relatively serious if caused by diseases. Glutamine aminotransferase, also known as aspartate aminotransferase, abbreviated as AST or GOT, has a normal range of zero to 40 units per liter. Glutamine aminotransferase is mainly found in the heart muscle, and to a lesser extent in the liver, skeletal muscle, kidneys and other tissues. Glutamine aminotransferase 44 is a mild elevation and may be the result of staying up all night. Physiological factors such as exertion lead to it. In addition, viral hepatitis, cirrhosis, autoimmune hepatitis, and drug-induced liver injury, alcoholic liver disease, etc. lead to destruction of liver cells and mitochondrial damage, which will release the glutamine aminotransferase in them, resulting in higher-than-normal values of glutamine aminotransferase in the serum. Extrahepatic injuries such as acute myocardial infarction will have elevated glutamine aminotransferase, which will also be accompanied by elevated CK (myrosinase) and CKMB (myrosinase isoenzyme). It is recommended to consult a doctor for diagnosis and treatment of elevated AAT.
