Extracellular Water Estimated by the Bromide Dilution Method from Samples of Urine, Saliva, And Plasma
Bromide (Br) dilution has been used by many investigators to estimate extracellular water (ECW) (Cheek et al., 1984; Brans et al., 1904; Schaffer et al., 1987). The use of this method in infants, however, is often limited by the need to take multiple blood samples. Our present studies were designed to 1) evaluate the accuracy and precision of Br measurements in micro-volumes of body fluids using ion chromatography, and 2) investigate urine and saliva as alternatives to plasma for the estimation of Br dilution space.
