Performing Lab
Sodium, Random Urine with Creatinine
Clinical Use
Order TestUse
The excretion of sodium varies with dietary intake and exhibits diurnal variation, with higher excretion during the daytime. Decreased urinary sodium levels may be observed in congestive heart failure, excessive sweating, diarrhea, pyloric obstruction, malabsorption, and primary aldosteronism. Elevated levels can result from high salt intake, adrenal gland failure, diabetic acidosis, salt-losing renal diseases, and dehydration due to water deficit.
