The normal value may differ slightly depending on your lab. For a one-time urine sample, the normal urine sodium value is around 20 mEq/L. For the 24-hour urine test, the norm ranges from 40 to 220 mEq/L per day. The wide range reflects your dietary salt intake.

The concentration of sodium (Na) in blood serum/plasma is determined by ion-specific electrode (ISE) technology that measures the physiologically important activity of sodium ions
