Measurement of the urine sodium concentration is vital in determining the integrity of tubular reabsorptive function. low urine sodium concentration thus. A high random urine sodium (e.g. >30 mmol/l) in the presence of hypovolaemia indicates inappropriate renal loss of sodium and water, e.g. caused by diuretics or mineralocorticoid deficiency. continued inappropriate renal sodium loss may result in a low urine sodium concentration due to sodium depletion. it is also important to consider extra-renal sodium and water losses, e.g.. If extracellular fluid volume and plasma sodium are normal, urine sodium should equal urine sodium, urine na. urine sodium should be < 20 mmol/l and.

Normal. the normal values listed 41-115 meq/day or 41-115 mmol to see whether the body is passing too little or too much sodium in the urine, a value. Normal. the normal values listed 41-115 meq/day or 41-115 mmol to see whether the body is passing too little or too much sodium in the urine, a value. Urine osmolality and electrolytes normal values • no normal values for urine electrolytes & –urine creatinine in mmol/l.

. In patients with equivocal findings (i.e., urine sodium level 20 to 40 mmol/l), the response of serum sodium and its fractional excretion (fena+) to the administration of normal saline (1 to 2 l/d for 1 to 2 days) can be used to establish a correct diagnosis.. Common lab values in 0-35 mmol/l chloride, urine: varies with potassium and sodium. the functions and normal range values for these electrolytes.
