24 Hrs Urinary Sodium/Potassium Test in Kathmandu

About this test

This test measures how much sodium and potassium your kidneys pass out in the urine over a complete 24-hour period, giving a far more reliable picture than a single random sample because levels swing widely through the day with meals and fluids. Because dietary salt is the main driver of urinary sodium, the 24-hour figure is the best objective check of how much salt a person is actually eating — useful when blood pressure stays stubbornly high despite treatment, or when a doctor wants to confirm whether salt-restriction advice is being followed. It is also a core investigation for patients with recurrent kidney stones, where high sodium excretion drives calcium into the urine, and for working up unexplained low or high blood potassium. When read alongside blood electrolytes, it helps separate kidney-related potassium loss from intestinal causes, and supports the diagnosis of conditions such as primary aldosteronism (Conn's syndrome), Bartter and Gitelman syndromes, and the kidney effects of long-term diuretic use. In Nepal, where salt-heavy diets, pickles, preserved and packaged foods push average intake well above recommended limits, this test is a practical tool in hypertension and chronic-kidney-disease clinics to guide lifestyle counselling with real numbers rather than guesswork. The single most important factor for an accurate result is the collection itself: missing even one or two urinations, or losing the first morning sample, can throw the totals off. Results are usually interpreted with the patient's blood pressure, kidney function, medications and dietary history rather than in isolation.
