ast/alt ratio, is the ratio of alanine aminotransferase and glutamic aminotransferase in liver function tests, if the ratio is greater than 1, it may be caused by chronic hepatitis or cirrhosis. ast/alt ratio normal value of 1 to 1.5 ~ 2.5 between, ast/alt ratio of 1: 1.8 consider severe liver injury, is more serious. If ast continues to rise, ast/alt ratio is greater than 1, it means that chronic hepatitis patients have symptoms, such as loss of appetite, abdominal distension, fatigue, etc., and suggests that the liver cells may have been necrotic, and should be timely hospital diagnosis and treatment. If the ratio of ast/alt ratio reaches 1 to 1.2~2.3, it means serious liver injury, which must be treated in time, otherwise it will induce acute liver failure, and the serious condition may even lead to the patient’s death.
