Chloride
Chloride is an electrolyte that helps maintain fluid and acid–base balance. Its relationship with sodium and bicarbonate is often the reason for the test.

Understanding the test
What does the Chloride test measure?
Also called Blood Chloride Electrolyte
Fluid loss, kidney disease and some medicines can alter chloride. A clinician may order it as part of an electrolyte assessment after vomiting or diarrhoea.
When it may be requested
Hydration changes
Chloride may change with sodium and water after significant fluid loss.
Acid–base changes
Chloride and bicarbonate can move in relation to one another when acid–base balance is disturbed.
Before your sample
Prepare for collection
SpecimenSerum
Your checklist
Drink as you normally would unless you have a prescribed fluid restriction. Tell the team about recent vomiting, heavy fluid losses, diuretics or intravenous fluids. Chloride alone needs no fast.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
Chloride is usually read with sodium and bicarbonate. A pattern across these markers helps distinguish water-balance changes from acid–base disturbances.
What can affect it
- One chloride result cannot identify the cause of a fluid or acid–base problem.

Patient questions
Before you book
What else helps explain a chloride result?
Recent vomiting, diarrhoea, fluid treatment and certain medicines can affect the balance. The accompanying sodium, potassium and bicarbonate results supply context.
Does heavy sweating in the heat affect chloride?
Sweating loses both water and salts. How chloride changes depends partly on what you have lost and replaced. Tell the clinician about heavy sweating or other fluid loss, and continue any fluid plan you have been prescribed.
Can diuretics or blood pressure medicines affect chloride?
Yes. Diuretics increase chloride loss through the kidneys and are one of the commonest reasons for a low result, and other blood pressure medicines, steroids and laxatives can also shift the electrolyte pattern. Tell the collection team what you take so the result is read in context; your doctor decides whether any change is needed, not the test alone.
