What causes the low ratio of 0.5 to 0.5?

ALT mainly reflects the liver function of patients. Under normal circumstances, the ratio of AST/ALT is less than one. As long as the value of AST is not abnormal, there is no need to worry about the small ratio. It may be caused by diet, drinking and other factors. If there is abnormal liver function, it may be related to hepatitis and other diseases.
