What is the AST test used for?

The AST test measures the amount of AST in your blood that has been released from injured tissue. An older name for the test is serum glutamic-oxaloacetic transaminase (SGOT) test. What is the purpose of the AST test? Doctors commonly use the AST test to check for liver conditions, such as hepatitis.

Why do doctors check Alt and AST levels?

For this reason, healthcare professionals may also test levels of alanine aminotransferase (ALT), another liver enzyme. ALT levels occur in higher concentrations in the liver. Looking at both ALT and AST levels can give a doctor a clearer idea of overall liver function and health.

What is AST differencing?

AST differencing, or for short tree differencing, consists of computing the list of differences between two ASTs. This list of differences is typically called an edit script. The edit script directly refers to the AST of the code. For instance, an edit action may result in the addition of a new AST node representing a function.

What is AST ALT ratio?

The AST:ALT ratio (De Ritis ratio) may assist in differentiating the site of biliary obstruction. When associated with a cholestatic picture, an AST:ALT ratio of <1.5 suggests an extrahepatic obstruction. In such circumstances the ALT titre is frequently considerably higher than AST.
