What Is a Sodium Test?
A sodium test is a simple blood test that measures the amount of sodium in your blood. Sodium is an essential electrolyte that helps your body maintain proper fluid balance, supports nerve function, and enables muscle contractions.
This test helps detect sodium imbalances in your body and is a regular part of full-body checkups to detect underlying health conditions, like kidney disease, dehydration, or heart problems. The test uses a blood sample drawn from a vein in your arm.
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

• Nausea and vomiting
• Headache and confusion
• Fatigue or extreme tiredness
• Muscle weakness, spasms, or cramps
• Excessive thirst and dry mouth

Why Is a Sodium Test Done?
A sodium test helps doctors diagnose electrolyte imbalances and monitor treatment effectiveness for conditions affecting your body's fluid balance.
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.
