What is aminotransferase? In the liver function test, we always see the word transaminase, and we all know that elevated transaminase means liver problems. But what exactly is transaminase? Professor Li Guangming said that transaminase is an essential “catalyst” in the body’s metabolic process and is mainly found in the liver cells. The aminotransferase usually stays in the liver cell pulp, under normal circumstances is not run out. However, if the liver cells are broken, transaminases will be released and will show up as elevated in the medical report. So how much transaminase is elevated means how many liver cells have been destroyed. The more destruction, the higher the aminotransferase will be. When liver cells are destroyed to a certain extent, liver function will be affected. What is the difference between glutamic aminotransferase and glutamic alanine aminotransferase? Although they are both branded as transaminases, they reflect the root cause of the problem differently. In fact, transaminases are not only found in the liver, but also in other organs and tissues. Some people with heart problems may also have elevated glutathione. What level of transaminase is high enough to cause concern? Aminotransferases are sensitive and there are other factors, such as taking certain medications or strenuous exercise, that can cause an increase in aminotransferases. Transaminases can return to normal by stopping medication or resting. So what value of aminotransferases should we be highly concerned about? A persistent increase in transaminases is dangerous. If the level is just a little high, the situation can be checked again after a month or two to avoid some influencing factors. If the aminotransferases are persistently high for several times, we should highly suspect liver and biliary diseases or diseases of the heart or other organs, and further follow medical advice for treatment. The second test index: bilirubin, albumin, coagulation function liver function includes two major blocks: transaminases are mainly how many liver cells are destroyed, and some indicators can reflect how many liver cells are still normal. It also reflects the reserve function of the liver. Bilirubin, albumin, and coagulation are all indicators of the liver’s reserve function. If the reserve function of the liver is affected, it means that the liver damage is serious. For example, if a patient with fatty liver has elevated bilirubin, lowered albumin and abnormal coagulation, it means that the fatty liver has most likely progressed to the level of cirrhosis.
