Test Description: Sodium Urine 24 Hours

The Sodium Urine 24-Hour test measures the amount of sodium excreted in the urine over a 24-hour period. It helps evaluate the body’s sodium balance, kidney function, and the body’s ability to regulate electrolytes. This test is commonly used to assess conditions such as dehydration, kidney disease, heart failure, and hypertension. High sodium levels in urine may indicate excessive salt intake or kidney problems, while low levels could suggest conditions like adrenal insufficiency or dehydration. The 24-hour collection provides a more accurate assessment of sodium excretion compared to a single urine sample.
