24-Hour Sodium Intake Assessment (Qualitative/Quantitative)

What This Test Measures

This test evaluates the total sodium intake from all food and beverages consumed in a 24-hour period. Sodium is a mineral essential for nerve and muscle function, but excessive intake can contribute to high blood pressure or other health risks. The test does not measure sodium levels in your body fluids (like blood or urine) but focuses on what you eat and drink.

Why It’s Done

Healthcare providers may order this test if you have or are at risk for conditions like high blood pressure, heart disease, or kidney problems. It can also help determine whether you’re meeting dietary sodium guidelines or if you need adjustments to your diet.

How It’s Done

You’ll be given detailed instructions on how to record everything you eat and drink for 24 hours, including snacks, drinks, and medications that contain sodium. You’ll likely need to weigh and log all foods/drinks, and some labs may provide a urine collection kit if additional sodium excretion data is needed.

What to Expect

No special preparation is needed beyond following the instructions carefully. Results are typically reviewed by your doctor to compare against recommended sodium intake levels (varies by age, health status, and diet plan).
