Also Known As

Cl Test, Serum Chloride Test

The Purpose of a CI Blood Test

Your body relies on electrolytes to maintain optimal fluid and pH balance. Common electrolytes include sodium, potassium, and chloride. Chloride is a marker that’s often tested as part of regular health checkups, but it can also be used to diagnose and help treat certain medical conditions. Among them:

  • Heart failure
  • High blood pressure
  • Liver or kidney disease
  • Metabolic disease
  • Diabetic acidosis

Chloride, Serum (001206)

What Does Chlolide Blood Work Measure?

The Cl blood test checks the level of chloride in your blood.

Who Should Take a Cl Lab Test?

You may want to take a chloride lab test if you’re experiencing the signs and symptoms of an electrolyte imbalance, including:

  • Dehydration
  • Fatigue
  • Chronic vomiting
  • Diarrhea
  • Difficulty breathing

Doctors often recommend a comprehensive test every year to check chloride and other health markers. Chloride is often included as part of a standard electrolyte panel or metabolic panel.

Chloride Lab Test Preparation

You don’t need to take any special precautions prior to your Cl blood work.

Chloride Blood Work Results

Normal results typically fall between 96 and 106 mEq/L. Lower numbers may indicate issues such as lung disease, heart failure, or Addison disease. High chloride levels can signal kidney disease, metabolic acidosis, or significant dehydration.

Depending on the results, you may need to get further blood work, such as diabetesheart health, or kidney function tests. If you need help determining your next steps, schedule a telehealth visit with one of our board-certified doctors.
