About this test

What is this test for?

Abnormal sodium levels may indicate dehydration, kidney dysfunction, hormonal imbalance (such as adrenal disorders), or fluid overload. Results are typically interpreted alongside potassium and other electrolytes to assess overall metabolic stability.


What does this test measure?

Sodium is a key electrolyte that helps regulate fluid balance, nerve transmission, and muscle function. The test measures the concentration of sodium in the bloodstream, which reflects overall fluid and electrolyte balance.


When is this test recommended?

Sodium testing is commonly included in routine blood panels when assessing hydration status, kidney function, or symptoms such as confusion, weakness, headaches, or unexplained fatigue. It may also be monitored in individuals taking certain medications, including diuretics.
