- Enter Urine Sodium Concentration (in mmol/L) — e.g., 100. This value comes from your lab report.
- Enter 24h Urine Volume (in liters) — e.g., 1.5. Use the total volume collected over 24 hours.
- Click "Calculate Sodium Excretion".
- Your result appears as mmol/24h, along with the formula used.
Note: All inputs must be non-negative numbers. Use metric units only (mmol/L and liters).

Frequently Asked Questions
Sodium excretion is the amount of sodium eliminated in the urine over 24 hours. It reflects dietary sodium intake.
It is calculated by multiplying urine sodium concentration (mmol/L) by total urine volume (L) over 24 hours.
Normal values vary but typically range from 40-220 mmol/24h depending on diet. Consult your doctor for interpretation.
