The reference range for urine sodium is 40-220 meq/l/24 hours. next: interpretation.. A spot urinary sodium test is available that allows urinary sodium to be quickly and conveniently measured in a random urine sample. hypovolaemic hyponatraemia: urinary sodium >20 mmol/l (>20 meq/l) indicates renal sodium losses and urinary sodium ≤20 mmol/l (≤20 meq/l) indicates extrarenal sodium losses..

Document agreed by: l bailey sodium (urine) description major extracellular cation. measured as part of urine u&e a high random urine sodium (e.g. >30 mmol/l). Overall, age, gender, ethnicity, diastolic blood pressure, height, weight, bmi, serum creatinine, spot urine sodium, spot urine chloride, and spot urine osmolality were associated with 24-hour urine sodium excretion ; however, spot urine sodium-to-creatinine ratio (p = .0587) and spot urine chloride-to-creatinine ratio were not (p = .0637).. 50 – 99 mg/mmol creatinine = significant proteinuria. repeat using early am sample. consider acei or arb in hypertension. 100 – 300 mg/mmol creatinine = high proteinuria. if new finding, seek nephrology advice regardless of egfr. >300 mg/mmol creatinine = “nephrotic range” proteinuria. if new finding, seek nephrology advice regardless of egfr..
Urine na + >40 mmol/l in oliguria suggests acute tubular necrosis. 3,6 (however, spot urine sodiums without other data have been criticized for their applicability to this diagnosis.) low na + excretion may be found with early obstructive uropathy and with the oliguria of acute glomerulonephritis 3 and in some patients with x-ray contrast acute renal failure.. A test for potassium in the urine is a 24-hour test or a one- time (spot) test that measures the amount of potassium (an electrolyte and mineral) in the urine.. chemistry . normal values: urine: sodium . 120 : 136-146 mmol/l : sodium 60 mmol/l potassium 30 mmol/l osmolality 500 mosm/kg: potassium : 3.9 : 3.5-5.3 mmol/l.. Ur en med 21311:2-25 correlation of 24-hour urine sodium, potassium and calcium measurements with spot urine 21 sodium, potassium and calcium were studied in three.
