A test for sodium in the urine is a 24-hour test or a one-time (spot) test that checks how much sodium is in the urine. Sodium is both an electrolyte and a mineral.

Normal

Normal results may vary from lab to lab. Results are ready in 1 day.

40–220 milliequivalents (mEq)/day or 40–220 millimoles (mmol) (SI units)

Many conditions can affect sodium levels. Your doctor will talk with you about any abnormal results that may be related to your symptoms and medical history.
