Understanding the test
What does the Sodium test measure?
Also called Blood Sodium Electrolyte
Sodium may be requested after fluid loss, with kidney or heart conditions, or during treatment affecting water balance. Changes in the amount of body water are often central.
When it may be requested
Medicines affecting fluid balance
A clinician may monitor sodium during diuretic treatment.
Recent fluid disturbance
Symptoms after vomiting or changes in fluid intake may prompt an electrolyte assessment.
Before your sample
Prepare for collection
SpecimenSerum
Your checklist
No fasting is usually needed. Keep to your usual or prescribed fluid intake and tell the team about vomiting, diarrhoea, intravenous fluids or diuretic use.
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
A clinician interprets the result with fluid history, medicines and other electrolytes. The level cannot identify by itself whether a person needs more or less fluid.
What can affect it
- Sodium concentration is not a direct measure of dietary salt.

Open your laboratory report
Look for Sodium in your report. Use the sample type and collection time when comparing it with an earlier report.

Discuss the next step
Tell the clinician about recent fluid losses or changes in medicines instead of adjusting salt or water intake from the number alone.

Patient questions
Before you book
Does a high result measure how much salt I eat?
It is a concentration, so changes in water balance can change the reading. Your clinician considers fluid loss, medicines and other results before suggesting an explanation.
Can medicines affect sodium levels?
Yes. Diuretics are the best known, but antidepressants, some anti-epileptic and antipsychotic medicines can also lower sodium, often by making the kidney hold on to water. A recent change in dose matters too. Bring a complete medicine list to the test; if the result is abnormal, your doctor decides whether any medicine needs reviewing.
What symptoms need urgent attention with a low sodium result?
Sudden confusion, a seizure or loss of consciousness needs emergency assessment. When sodium falls rapidly, it can affect the brain. Treatment depends on symptoms and how quickly the level changed. Do not try to correct the number yourself by drinking extra water or taking salt.
