Urine Sodium Levels Mmol L. Syndrome of inappropriate ADH secretion SIADH. In range is 1600 23 reference range ml 5-79bcemmol creatinine. If Urine Na 30 mmol L and urine osmolality significantly higher than serum osmolality this suggests SIADH Consider Addisons disease and hypothyroidism Consider effects of drug therapy Consider reset osmostat syndrome in patients with chronic illness and stable hyponatraemia. Patients with euvolaemic hyponatraemia always have a urinary sodium 20 mmolL 20 mEqL.
If Urine Na 30 mmol L and urine osmolality significantly higher than serum osmolality this suggests SIADH Consider Addisons disease and hypothyroidism Consider effects of drug therapy Consider reset osmostat syndrome in patients with chronic illness and stable hyponatraemia. Normal serum sodium levels are 135145 mmolL 135145 mEqL. Normal urine sodium levels is 40-220 mEqL per 24 hours 40 to 220 mmol24 hours 2. 30 mmolL in the presence of hypovolaemia indicates inappropriate renal loss of sodium and water eg. Monitoring of adequate sodium substitution is best carried out by measuring the concentration of sodium in spot urine. Creatinine 24-hour urine 033l 063-250 g24 h what does this mean.
Adult 40 to 220 meqday 40 to 220 mmol24 hours.
Levels higher than 10 mmoll sodium signify an adequate oral sodium intake. SIADH needs to be confirmed by results of paired serum and urine samples. The normal urinary concentration of an euvolaemic individual will decrease to about 10mmolL if the dietary sodium is restricted. Urine sodium interpretation Normal urine sodium. Normal serum sodium levels are 135145 mmolL 135145 mEqL. Sodium is the major extracellular cation and functions to maintain fluid distribution and osmotic pressure.
