What Does the Sodium Test Measure?
The sodium test provides valuable information about your body's electrolyte balance by measuring:
• The concentration of sodium in your blood serum
• Your body's ability to maintain proper fluid balance
• How well your kidneys are regulating sodium levels
• Whether you have an adequate hydration status
• The functioning of your heart and nervous system

Importance of a Sodium Test
The sodium test is clinically important because it provides crucial insights into your overall health. Since your body maintains sodium levels within a very narrow range, even small changes can signal significant health conditions.
This test helps healthcare providers diagnose the cause of symptoms like confusion, muscle weakness, or nausea. It also helps monitor patients with known kidney, heart, or liver conditions, ensuring their treatments are working effectively and preventing serious health risks or complications.
