What Is The Sodium Test For?
Sodium is essential to normal bodily function, playing a critical role in the maintenance of normal blood pressure. Sodium also helps regulate your body's fluid balance and aids in nerve and muscle communication.
Sodium levels in the blood, as well as all body water, are regulated by the kidneys ideally within a very narrow concentration range.
Abnormal blood sodium is usually due to an issue with hormone production or thirst and results in too little (dehydration) or too much (edema) body water content.
