Overview

Chloride is an electrolyte that works alongside sodium to maintain your body's fluid balance and regulate blood pH. This test measures chloride levels as part of electrolyte and metabolic assessment.

Chloride moves with sodium in your body—where sodium goes, chloride follows. Together they control water distribution between cells and blood. Chloride also forms stomach acid and participates in acid-base balance through its relationship with bicarbonate, available across Australia.

Abnormal levels usually reflect dehydration, kidney problems, or metabolic disturbances rather than dietary issues.

Symptoms

To assess acid-base balance and electrolyte status, identify specific types of metabolic disturbance (hyperchloraemic metabolic acidosis or hypochloraemic metabolic alkalosis), and contribute to a complete electrolyte picture in the context of kidney, adrenal, or digestive conditions.

Questions

No fasting is required for a chloride blood test.
Stomach acid (hydrochloric acid) is made from hydrogen and chloride ions. When you vomit repeatedly, you lose chloride in the gastric fluid. This creates a relative excess of bicarbonate in the blood (metabolic alkalosis) and falls in blood chloride — a pattern called hypochloraemic metabolic alkalosis.
The anion gap is calculated as: sodium minus (chloride plus bicarbonate). It represents the unmeasured negatively charged ions in the blood. An elevated anion gap suggests accumulation of acids like lactate or ketones. A normal anion gap with acidosis suggests chloride retention or bicarbonate loss. Without chloride, this clinically important calculation cannot be made.
Dietary salt provides sodium chloride, but healthy kidneys rapidly excrete excess chloride to maintain normal blood levels. Blood chloride is regulated rather than directly reflecting salt intake in people with normal kidney function.
Chloride provides the most clinical value as part of a full electrolyte panel (alongside sodium, potassium, and bicarbonate) rather than as a standalone test. The pattern across all four electrolytes is used to characterise acid-base disturbances and electrolyte disorders.

How to prepare

No fasting is required. No specific preparation is needed. Take medications as normal.

After the test

Chloride results are interpreted as part of the full electrolyte picture. Share your results alongside sodium, potassium, and bicarbonate with your GP. In most healthy people having a routine panel, isolated chloride abnormalities are uncommon — the pattern across all electrolytes is what guides clinical decision-making.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Chloride is measured in millimoles per litre (mmol/L). The normal adult range is typically 98–107 mmol/L.

- Hyperchloraemia (above 107 mmol/L): High chloride. Associated with dehydration, kidney disease, diarrhoea (which loses bicarbonate more than chloride, relatively raising chloride), hyperchloraemic metabolic acidosis (such as from normal saline infusion or renal tubular acidosis), and hyperaldosteronism.
- Hypochloraemia (below 98 mmol/L): Low chloride. Most commonly caused by vomiting (loss of gastric hydrochloric acid), diuretic use, or metabolic alkalosis. Can also accompany hyponatraemia.
- Anion gap calculation: Sodium minus (chloride plus bicarbonate), used to categorise metabolic acidosis. A high anion gap suggests accumulation of unmeasured acids (lactic acid, ketones). A normal anion gap with low bicarbonate and high chloride suggests a different set of causes.

Adam O. ACT

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

Calcium Blood Test

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"

Frequently Asked Questions

Do I need to book ahead?

Most collection centres accept walk-ins. Some may require a booking - check details when you click on your chosen location.

How do I know if I need to fast?

If your test needs fasting, we’ll include that in your instructions after you order. Fasting usually means no food for 8–12 hours, but water is fine.

What do I need to bring?

Just your pathology referral form (we email it to you)

Can I bring someone with me?

Of course. Just maybe don’t bring the friend who faints at the sight of blood.

What’s a phlebotomist?

They’re the highly trained professionals who take your blood sample - with a steady hand and a sharp needle. They love blood, but don’t worry… they’re not vampires. Just legends who make blood tests quick, clean, and (almost) painless.

What other samples may I need to provide for my test?

Some of our tests include Urine, Stool, Saliva and more. Each test will have a clear description on what sample you will need to give and instructions on how.
