PRINCIPLE

The determination of electrolytes is one of the most important functions in the clinical laboratory. Methods for determining electrolytes include emission spectrophotometry, flame spectrophotometry, neutron activation analysis, atomic absorption spectroscopy, and ion selective electrodes. The ISE module for Na, K and Cl employs membrane electrodes that are specific for each ion of interest in the sample. An electric potential is developed according to the Nernst equation for a given ion. Compared to the internal reference solution, this electrical potential is translated into voltage and then into the ion concentration of the sample.

DIAGNOSTIC USE

Electrolytes affect most metabolic processes. They serve to maintain osmotic pressure and hydration of various body fluid compartments, adequate body pH, and regulation of appropriate cardiac and muscular functions. Electrolytes also participate in oxidation-reduction reactions and participate as essential parts or cofactors in enzymatic reactions.
