The significance of the transaminase ratio is to assist in the diagnosis of whether there is damage to the liver cells and whether there is any abnormality in the functioning of the liver. If there is any abnormality, it is important to seek medical attention for the appropriate treatment. The aminotransferase ratio is one of the indicators of liver function tests, which is the ratio of alanine aminotransferase to glutamine aminotransferase, and the normal ratio is 1.5-2.5:1. Generally speaking, if the aminotransferase ratio is less than 1, it may indicate that there are abnormalities in the liver function, which may be caused by acute and chronic hepatitis, cirrhosis, liver cancer, drug-induced liver injury, alcoholic liver disease, etc. Patients with abnormalities should consult a doctor. Patients with abnormal aminotransferase ratio need to consult a doctor to clarify the cause of the disease and have regular liver function and liver ultrasound checkups, usually pay more attention to rest, quit smoking and drinking, avoid overwork, and avoid staying up all night.
