An alanine aminotransferase indicator of 96 U/L is not normal. The normal value of alanine aminotransferase (ALT) is 0-40 U/L, and 96 U/L is considered an elevated alanine aminotransferase indicator. Glutaminase is found in many types of cells in the body, with hepatocytes having the highest levels and cardiomyocytes having the second highest levels. The liver contains about 100 times the amount of ALT than the blood, and when liver cells are destroyed, the ALT in the liver cells is released into the blood, causing its level in the blood to rise. Changes in serum ALT levels are a sensitive marker for diagnosing hepatocellular damage, and are often used as a reference for diagnosing toxic hepatitis, viral hepatitis, cirrhosis, liver cancer, and other diseases. In addition, myocarditis, cardiac infarction, myocarditis, heart failure, etc. can also cause a mild increase in alanine aminotransferase. Other causes of elevated ALT include prolonged or heavy drinking, biliary tract diseases, pneumonia, tuberculosis, typhoid fever and other diseases. In addition, after strenuous exercise, acute soft tissue contusion can also cause transient ALT elevation. Staying up all night, overwork, drinking alcohol and other reasons can also cause transient elevation of ghrelin, usually do not need special treatment. If the test found that the alanine aminotransferase index rose to 96U / L, please go to the hospital to seek medical help, systematic diagnosis and treatment, do not take it lightly, so as not to delay the condition.
