What To Think About


  • The results from a blood or urine chloride test do not provide enough information to diagnose a specific disease or problem. Your doctor will talk with you about how your results may be caused by your symptoms or medical history.
  • Potassium chloride (found in salt substitutes) can lower your blood chloride levels but raise your urine chloride levels.
  • Tests for sodium, potassium, and bicarbonate usually are done at the same time as a blood test for chloride. For more information, see the medical tests Sodium (Na) in Blood, Potassium (K) in Blood, and Bicarbonate.
  • The skin sweat test for chloride is used to test for cystic fibrosis. For more information, see the medical test Sweat Test.
