AST ALT ratio > 2 strongly suggests alcoholic hepatitis - an inflammation caused by the consumption of too many units of alcohol for a regular period of time. Too high AST ALT ratio with low levels of AST and ALT. Can be caused by factors located outside of the liver, such as hemolysis...
An AST:ALT ratio of 1.1 or less may be seen with alcohol abuse without cirrhosis. However, long-term alcohol abuse with cirrhosis was associated with an AST:ALT ratio of greater than 1.1. [xii] In alcoholics with elevated aminotransferases, the mean AST:ALT ratio was 1.5 while for those ...

it should be noted that most patients with high alcohol consumption but without severe liver disease often do not have an AST/ALT ratio above 1, which means that a high ratio could probably be a result of advanced alcoholic liver disease. ...
AST/ALT ratiowas first put forward in 1957 for the diagnosis of viral hepatitis[9]. Subsequently, a number of studies found that the ratio > 1.00 suggestedcirrhosisin patients withchronic viral hepatitis, non-alcoholic steatohepatitis (NASH),alcoholic liver disease(ALD) andprimary biliary cirrhosis...

Aims: To assess the place of AST/ALT ratio (the ratio of serum aspartate aminotransferase to serum alanine aminotransferase) as a diagnostic marker in medical populations. Methods: Laboratory tests were viewed retrospectively in three groups of patients: 313 patients with alcohol dependence, consecutive...

The aspartat aminotransferase (AST)/alanin aminotransferase (ALT) (De-Ritis) ratio (AAR) is an easily applicable blood test. An elevated AAR on the one hand has been associated with an increase in nonalcoholic fatty liver disease (NAFLD). NAFLD on the other hand is associated with an incre...
While ALT is predominantly found in the liver, meaning its elevation is a more direct sign of liver damage, AST is not exclusive to the liver. AST can also be found in significant amounts in the heart, muscles, and kidneys. 11 In medical tests, the ratio of ALT to AST can be essenti...
