WS/T 352-2011 Reference procedure for the measurement of catalytic activity concentration of alanine aminotransferase(No pyridoxal-5'-phosphoric acid)

Scope

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