About Beckman Coulter OSR6107 Olympus ALT Reagent Alanine Transaminase

Alanine aminotransferase (ALT) measurements are useful in the diagnosis and treatment of certain liver diseases (e.g., viral hepatitis and cirrhosis)

and heart disease. ALT is an enzyme involved in amino acid metabolism and is, therefore, found in many tissues. The highest levels of ALT are found in the liver and kidney tissues. Tissue destruction leads to the release of the intracellular enzyme into the circulating blood. Markedly elevated serum ALT levels may be found in a variety of diseases that involve the liver, such as hepatitis, mononucleosis, and cirrhosis. These very high levels of ALT are not usually observed in other disease processes, e.g. myocardial infarction, thus ALT is regarded as a reasonably specific indicator of liver disease.

Methodology: Beckman Coulter OSR6107 Olympus ALT Reagent Alanine Transaminase

This ALT procedure is based on principles outlined by Wroblewski and LaDue and utilizes a modification of the methodology recommended by the International Federation of Clinical Chemistry (IFCC).  ALT transfers the amino group from alanine to α-oxoglutarate to form pyruvate and glutamate. The pyruvate enters a lactate dehydrogenase (LD) catalyzed reaction with NADH to produce lactate and NAD+. The decrease in absorbance due to  the consumption of NADH is measured at 340nm and is proportional to the ALT activity in the sample.
