Sodium Test

The Sodium (Na⁺) Test measures the level of sodium in the blood, which is essential for fluid balance, nerve function, and muscle activity. Sodium is a key electrolyte that helps regulate blood pressure, hydration, and overall cellular function.

Why is the Sodium Test Important?

• High sodium levels (Hypernatremia) may indicate dehydration, kidney disease, Cushing’s syndrome, or excessive salt intake.
• Low sodium levels (Hyponatremia) may be due to heart failure, kidney disorders, liver disease, excessive fluid intake, or certain medications.
• Sodium imbalances can lead to confusion, fatigue, muscle weakness, seizures, or severe dehydration.

When is the Test Recommended?

• If a person has symptoms of dehydration, confusion, weakness, swelling, or abnormal blood pressure.
• Patients with kidney disease, high blood pressure, or heart problems may need regular monitoring.
• Often included in electrolyte panels and kidney function tests (KFT/RFT).
