A Designated Comparison Method for the Measurement of Ionized Calcium in Serum; Approved Standard
Provides a candidate designated comparison method to standardize the measurement of ionized calcium made by ion-selective electrode (ISE) potentiometry. This system can be used to assign ionized calcium concentrations to a commercially available, serum-based material to improve the traceability and transferability of results for the measurement of ionized calcium in the clinical laboratory. This standard Addresses the principle of the test, the assignment of ionized calcium concentrations to NIST Standard Reference Material 956a, the materials and methods used, and the results and conclusions of an interlaboratory study to assign the ionized calcium concentrations.
