Aspartate Aminotransferase (AST) Reagent

Key Benefits of the Aspartate Aminotransferase (AST) reagent

Wide measuring range

The upper healthy limit for AST is 37 U/l. The Randox Aspartate Aminotransferase (AST) assay can comfortably detect levels outside of the healthy range, measuring from 4.42 – 657 U/l.

Excellent stability

Stable until expiry date when stored at +2 to +8°C

Liquid ready-to-use reagents

The Randox AST reagent comes in a liquid format which is more convenient as the reagent does not need to be reconstituted which aids in reducing the risk of errors occurring

Other features of the Aspartate Aminotransferase (AST) reagent

  • UV (Modified IFCC)
  • Liquid and lyophilised reagents available
  • Stable until expiry date when stored at +2 to +8°C
  • Measuring range 4.42 – 657 U/l

What is the Aspartate Aminotransferase (AST) assay used for?

What is AST?

Aspartate Aminotransferase (AST), formerly known as serum glutamic oxaloacetic transaminase (GOT) is an enzyme found throughout the body.  The high concentration levels of AST are found in the liver and lower concentration levels are found in heart cells, red blood cells, muscle tissues and other organs including the kidneys and pancreas.

What is the AST assay used for?

Elevated concentrations levels of AST in the blood are directly correlated to the severity of the tissue or organ damage and can signal myocardial infarction, hepatic disease, muscular dystrophy and organ damage.  Excessive levels (10 times above the normal range) is indicative of liver damage including acetaminophen overdose, acute viral hepatitis or acute fulminant hepatitis, and tumor necrosis.  Moderately high concentration levels of AST are indicative of alcohol abuse, hemolysis, heart damage including heart attack or heart failure, muscle injury including trauma or muscle dystrophy.  Slightly elevated concentration levels of AST are indicative of cirrhosis, fatty change in the liver or mononucleosis.

The Randox AST assay is used for the quantitative in vitro determination of aspartate aminotransferase (AST) activity in serum and plasma.

AST often tested in combination with the alanine aminotransferase (ALT) test as part of the hepatic panel as ALT concentration levels are higher in most types of liver disease.  For more information on the validity and clinical utility of AST and ALT when assessing disease severity, please click here [external link].
