Metrological traceability of values for catalytic concentration of enzymes assigned to a calibration material

Background: The metrological traceability of values for the catalytic concentration of several enzymes assigned to a calibration material has been assured by following the recently published International Standard ISO 18153.

Methods: A traceable value with a measurement uncertainty was assigned for the catalytic concentration of alanine aminotransferase, creatine kinase, ?-glutamyltransferase and lactate dehydrogenase in two materials from different sources...
