[Direct and indirect ion selective electrodes methods: the differences specified through a case of Waldenström's macroglobulinemia].

Direct and indirect ion selective electrodes (ISEs) are two methods commonly used in biochemistry laboratories in order to measure the electrolytes such as sodium. In the clinical practice, it's the sodium concentration in plasma water -measured by direct ISE- which is important to consider as it is responsible of water movements between the liquid… (More)
