LOINC description : Measurement of intracellular sodium is performed in concert with the intracellular
measurement of potassium. Intracellular potassium is a marker for the development
of hypertension. The measurement is based on the fact that intracellular sodium is
very low compared to plasma sodium. When the cells are lysed in order to measure the
intracellular potassium, the hematocrit of the sample is determined by the dilution
of the plasma sodium by the now free intracellular sodium. (http://pubs.acs.org/doi/pdf/10.1021/ac900776d);
