The Sodium Test measures the sodium level in the blood, vital for maintaining fluid balance, nerve function, and muscle function. Sodium plays a key role in regulating blood pressure and volume, making this test important for diagnosing and monitoring conditions like dehydration, kidney disease, and blood pressure issues. A blood sample is drawn and analyzed to assess sodium concentration.

To ensure sodium levels remain within a healthy range and to support overall bodily function, it is recommended to undergo this test annually during routine checkups or as needed based on specific symptoms.
