Aminotransferases above 800 U/L will not affect normal life expectancy and can be gradually reduced to normal through treatment such as liver protection and symptomatic treatment of the cause. Transaminases mainly exist in liver cells. When liver cells are damaged by inflammation, poisoning and necrosis, transaminases will be released into the blood and make transaminases rise, so transaminases are a barometer of the liver and can reflect the damage of the liver in time. Transaminase is very sensitive, when the liver cell damage reaches 1%, transaminase can be doubled, so when transaminase is 800U/L or more, it only indicates that the liver has an inflammatory response, but it is not a fatal damage. For example, in liver failure, the bilirubin will be significantly higher and the albumin will be significantly lower, which is more dangerous than the elevated transaminases. So if the aminotransferase alone is elevated, it will not be life-threatening.
