Electrolytes
This panel measures sodium, potassium and chloride together. Their pattern can help evaluate fluid changes, kidney problems or the effects of medicines.

Understanding the test
What does the Electrolytes test measure?
Also called Sodium, Potassium & Chloride
A clinician may request the panel after fluid loss or to follow a medicine that affects salt and water balance. The three results are measured on the same sample.
When it may be requested
After vomiting or diarrhoea
The clinician can assess several salts together following fluid loss.
Diuretic monitoring
Some water tablets can alter sodium and potassium in different ways.

Before your sample
Prepare for collection
SpecimenSerum
Your checklist
No fast is required for this panel alone. Tell the team about diuretics, blood pressure medicines, potassium supplements and any recent change in fluid intake.
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
Sodium, potassium and chloride have different roles and can change in different directions. A result that needs urgent follow-up should be handled on the clinician's instructions.
What can affect it
- An electrolyte pattern helps guide investigation but cannot identify a person's fluid needs by itself.

Discuss the next step
Bring your medication list, especially diuretics. Ask whether one electrolyte needs checking again or whether the whole pattern should be followed.

Patient questions
Before you book
Which electrolytes are in this particular panel?
Intel Lab lists sodium, potassium and chloride. Magnesium and ionized calcium have separate test entries when those are the measurements your clinician requests.
What does a high or low potassium mean?
Both high and low potassium can affect your heart’s rhythm. A high potassium can follow reduced kidney clearance, potassium-sparing diuretics, ACE inhibitors, potassium supplements or adrenal insufficiency, or can be falsely raised by a difficult draw. A low potassium often follows vomiting, diarrhoea, thiazide or loop diuretics, or excess aldosterone or cortisol.
Why was I asked to repeat my potassium test?
Potassium is packed inside red blood cells, so if some cells break during a difficult draw or the sample sits too long before processing, the reported value rises without your body having changed. A fresh sample can check whether this happened. Follow the timing your clinician gives you. If you have been told to seek urgent care for a high result, go as directed even if you feel well.
