Sodium

The urine sodium test measures the concentration of sodium in a urine sample. Sodium is an essential electrolyte that plays a key role in regulating fluid balance, blood pressure, and normal nerve and muscle function.

This test is used to assess electrolyte and fluid status, evaluate kidney function, and assist in the investigation of disorders affecting sodium balance.

Patients are advised to contact the laboratory for specimen collection instructions prior to booking an appointment.

The findings related to these particular clinical tests are a general guide and do not cover every possible scenario, this is because every patient is unique and these results only have true clinical significance when combined with the patient’s full medical history, a physical exam, and other diagnostic findings.
