Then make proportion calculation. The plasma volume is calculated by evans blue technique the proportion of plasma and hematocrit is by centrifugation. Volume measurement of compartments. Everyone should have one. If the tracer is metabolised a series of measurements can be made and assuming exponential decline first order kinetics the volume of distribution can be determined by extrapolation back to zero time. Not interfere with body fluid distribution if the tracer is excreted in the urine then the loss can be determined and corrections made in the calculation.

Extracellular fluid volume measurement. Previous electrical impedance studies that predict body fluid volume and body fat used a single measurement site between the wrist and ankle calculations based on an electrical model of the thorax suggest that with a single wrist to ankle measurement only the electrical characteristics of the legs and arms will contribute significantly to a prediction of the total body fluid volume.
