Service Providers for 24 hrs. Urinary Sodium (Na)
24-Hour Urinary Sodium (Na) is a test that measures the amount of sodium excreted in the urine over a 24-hour period. Sodium is an essential electrolyte that helps regulate fluid balance, blood pressure, and nerve function. This test is commonly used to assess kidney function, hydration status, and conditions such as hypertension, renal disease, or adrenal disorders like Conn's syndrome. The test requires collecting all urine over 24 hours, and while no special preparation is typically needed, certain medications or diets may affect sodium levels and should be discussed with a healthcare provider before the test.
