The reason for a normal color ultrasound of 179 U/L for alanine aminotransferase is the early stage of impaired liver function, which has not yet shown imaging changes, and common factors include viruses and medications. The full name of the enzyme alanine aminotransferase is alanine aminotransferase, which can be found in all kinds of cells throughout the body, especially in hepatocytes with the highest level, therefore, alanine aminotransferase is a sensitive marker for checking liver disease. A normal color ultrasound of 179 U/L for alanine aminotransferase is overwhelmingly caused by liver damage, such as viral hepatitis and drug-induced hepatitis. If there is minor damage to the liver cells, the alanine aminotransferase passes through the damaged liver cells and into the bloodstream, resulting in elevated serum alanine aminotransferase, when there may not yet be any significant change in the color ultrasound of the liver. When the patient has a pathologic liver injury due to viral hepatitis, drug-induced hepatitis and other diseases, it may manifest as elevated ghrelin. The patient should follow the doctor’s instructions to actively carry out the next step of treatment, including Hepatitis B 5, Hepatitis B virus DNA and liver imaging tests, etc., in order to clarify the organic lesions of the liver and prevent further aggravation of liver injury. When the physical examination reveals that the glutamic aminotransferase 179U/L color ultrasound is normal, it is necessary to consult the doctor in time, who will analyze and judge the situation, and carry out appropriate treatment according to the cause of the disease.
