WS/T 353-2011 Reference procedure for the measurement of catalytic activity concentration of aspartate aminotransferase(No pyridoxal-5’-phosphoric acid)

Scope

This standard specifies the reference method for determining the catalytic activity concentration (without pyridoxal phosphate) of aspartate aminotransferase (AST) in clinical medical applications.
This standard is mainly applicable to reference laboratories, serving as a traceability for the determination of the catalytic activity concentration (without pyridoxal phosphate) of aspartate aminotransferase. It can also be used as a traceability for instrument and reagent manufacturers related to the testing of enzyme catalytic activity concentration, and is available for application by relevant accreditation units and quality management departments.
