CLSI C29 Abstract

Standardization of Sodium and Potassium Ion-Selective Electrode Systems to the Flame Photometric Reference Method; Approved Standard—Second Edition (CLSI document C29-A2) offers a protocol for standardizing instruments that contain direct ion-selective electrodes to give results in concentration terms that are verifiable to the reference method (flame photometry) for specimens with normal plasma water (i.e., lipids and proteins). The document describes the preparation of serum pools to carry out the procedure. Laboratories without the resources, equipment, or personnel to prepare the pools can purchase them from the National Institute of Standards and Technology (Gaithersburg, MD). It is recommended in C29-A2 that the accuracy of each new direct potentiometric instrument be verified with these standard pools, together with the flame photometer, if it is also used to report patient results.
