What is a Sodium Level Test?

Sodium (Na+) blood test checks for how much sodium is in your body. Sodium is an electrolyte in our body that is essential to life. It is important to the distribution of water in the body, osmotic pressure, neuromuscular function, acid-base balance, and electrolyte balance. Severe imbalance lead to permanent neurological deficits.

Decreased Sodium Level:

  • Diarrhea
  • Vomiting
  • Nasogastric suction
  • SIADH
  • Presence of diuretics in the blood
  • Congestive heart failure

Increased Sodium Level:

  • Excessive dietary or IV intake
  • Cushing’s Syndrome
  • Diabetes insipidus
  • Excessive sweating

Who should get this test?

  • Check the water and electrolyte balance of the body.
