Chloride Test

Brief Summary:

A chloride test measures the level of chloride in your blood or urine. Chloride is one of the most important electrolytes in the blood. It helps keep the amount of fluid inside and outside of your cells in balance. It also helps maintain proper blood volume, blood pressure, and pH of your body fluids. Tests for sodium, potassium, and bicarbonate are usually done at the same time as a blood test for chloride.

 

Technical Purpose:

To determine if there is a problem with your body’s electrolyte balance or acid-base (pH) balance and to monitor treatment; as part of a routine health checkup. This test detects abnormal blood chloride levels for your doctor to diagnose certain health conditions. These conditions include alkalosis, which happens when your blood is either too alkaline or basic and acidosis, which happens when your blood is too acidic. The blood test can also be used to monitor conditions such as:

  • high blood pressure
  • heart failure
  • kidney disease
  • liver disease

 

Test Process:

The health professional taking a sample of your blood will:

  • Wrap an elastic band around your upper arm to stop the flow of blood. This makes the veins below the band larger so it is easier to put a needle into the vein.
  • Clean the needle site with alcohol.
  • Put the needle into the vein. More than one needle stick may be needed.
  • Attach a tube to the needle to fill it with blood.
  • Remove the band from your arm when enough blood is collected.

 

Test Outcome/Results:

A chloride test measures the level of chloride in your blood or urine. Chloride is one of the most important electrolytes in the blood, along with sodium, potassium, and calcium. Chloride helps keep the amount of fluid inside and outside of your cells in balance. The normal range for blood chloride is between 96 and 106 milliequivalents of chloride per liter of blood (mEq/L).

A chloride level that’s above normal means there’s too much chlorine in your blood, which is called hyperchloremia. A low chloride level indicates that you have too little chloride in your blood, which is called hypochloremia.
