SODIUM

The sodium test measures the level of sodium, an essential electrolyte, in the blood. Sodium is crucial for maintaining fluid balance, nerve signaling, and muscle function. This test is used to diagnose and monitor conditions affecting sodium levels, such as hypernatremia and hyponatremia. Elevated sodium levels can indicate dehydration, kidney dysfunction, or excessive sodium intake, while low levels suggest conditions such as overhydration, heart failure, or SIADH (syndrome of inappropriate antidiuretic hormone secretion). The sodium test provides valuable information for assessing overall health, diagnosing underlying conditions, and guiding treatment decisions.
