About This Test
The Sodium (Na⁺) blood test measures the concentration of sodium in the blood.
Sodium is a major electrolyte and the main cation in extracellular fluid. It plays a vital role in maintaining:
Fluid and electrolyte balance, blood pressure regulation, nerve and muscle function, acid-base balance.
Sodium levels are tightly controlled by the kidneys, under the influence of hormones such as aldosterone, antidiuretic hormone (ADH), and natriuretic peptides.
Decreased sodium include diarrhea , and other causes of excessive fluid retension . Common causes of increased sodium include excessive fluid loss , high salt and increased kidney resorption .
