Up to now, Hyponatremia differentially diagnosed by physical examination, plasma and urine osmolalities, Echocardiography and biochemical measurements.~The purpose of this study is to determine whether bioimpedance spectroscopy can be used for the detection of hypovolemia and hypervolemia for the differential diagnosis of hyponatremia.
We aimed to investigate the role of bioimpedance spectroscopy for the diagnosis of hyponatremia
