The Sodium test measures the level of sodium in the blood, an essential electrolyte that helps regulate fluid balance, nerve function, and muscle contraction. Sodium also plays a key role in maintaining normal blood pressure and acid–base balance.
This test is commonly used to assess hydration status, kidney function, and electrolyte balance. Abnormal sodium levels may be associated with dehydration, kidney disease, heart conditions, hormonal imbalances, or certain medications. Sodium testing is often ordered as part of an electrolyte panel, basic metabolic panel, or comprehensive metabolic panel.
