At AIMS Diagnostic Center, the Sodium (Serum) Test is a vital clinical biochemistry test used to assess your body’s fluid and electrolyte balance. Sodium is an essential mineral that helps maintain normal blood pressure, supports nerve and muscle function, and regulates the amount of water in and around your cells.

- Kidney & Adrenal Assessment: Evaluates renal clearance efficiency and adrenal gland hormone regulation.
- Dehydration & Fluid Retention Check: Helps diagnose causes of severe fluid loss, swelling (edema), or sudden confusion.
- Medication Monitoring: Tracks electrolyte fluctuations in patients taking diuretics or blood pressure medications.
