WebA urinary sodium of <20mmol/L in a dehydrated patient is consistentwith functional renal tubules which will respond to rehydration whilst a urinary sodium of >20mmol/L (typically >50mmol/L) in conjunction with a low/normal urea and/or urate is indicative of SIADH. It is also used to monitor compliance with a low salt diet in hypertensive patients. WebCSF/S glu = 0.6. The fractional excretion of sodium (FE Na) is the percentage of the sodium filtered by the kidney which is excreted in the urine. It is measured in terms of plasma and urine sodium, rather than by the interpretation of urinary sodium concentration alone, as urinary sodium concentrations can vary with water reabsorption.
