The ALT is a cellular enzyme, found in highest concentration in liver and
kidney.
High levels are observed in hepatic disease like hepatitis, diseases of
muscles and traumatisms; its better application is in the diagnosis of the
diseases of the liver.
When they are used in conjunction with AST aid in the diagnosis of infarcts
in the myocardium, since the value of the ALT stays within the normal limits
in the presence of elevated levels of AST1,4,5.
Clinical diagnosis should not be made on a single test result; it should
integrate clinical and other laboratory data.
