Glutathione aminotransferase, also known as aspartate amino acid transferase, is an important indicator in liver function tests, and its normal value is 0-40 U/L, so the value of glutathione aminotransferase test can be zero, but some hospitals have test instruments that locate the reference value of 10-40 U/L, and below 10 there will be a low arrow indicator, at this time, low glutathione aminotransferase is not clinically significant and belongs to the normal situation. Glutathione is present in all tissues of the body, mainly in the heart muscle, followed by the liver, skeletal muscle and kidney tissue. In hepatocytes 80% of glutathione is found in the mitochondria of hepatocytes. Under normal circumstances, serum levels of transaminase are low, but when the body develops diseases such as liver disease, heart muscle or skeletal muscle injury, transaminase is released from the tissues into the bloodstream, resulting in higher than normal lab tests. Elevated transaminases can be seen in various acute and chronic hepatitis, alcoholic liver disease, cirrhosis, fatty liver and other liver diseases, as well as in acute myocardial infarction, dermatomyositis, kidney infarction, hyperthyroidism and other diseases. In addition, the presence of fever, strenuous exercise, exertion, alcohol consumption and medication can also cause transient aminotransferase elevation, which can gradually return to normal after eliminating the above-mentioned adverse factors. The key to elevated aminotransferases is to identify the cause of the disease and then carry out precise treatment. From the above, it can be seen that low transaminase is not clinically significant and is caused by different reference standard values of laboratory instruments, so no special treatment is needed.
