Test Overview – This test helps check the levels of electrolytes or essential minerals in the body that help the cells absorb nutrients. Healthy levels of electrolytes are important to stabilise the body’s water balance and the body’s acid/base (pH) level.

The electrolytes tested include sodium, potassium, chloride and bicarbonate.

When is it recommended? – Early morning or as per doctor’s advice.

Diagnostic ailment – high blood pressure, heart or kidney disease, electrolyte imbalance.

Significance – This test helps check the level of critical minerals in the body for healthy functioning.

What does the test result mean?

Sodium: The recommended level is 135 – 145 mmol/L.

Potassium: The recommended level is 3.5 – 5.0 mmol/L.

Chloride: The recommended level is 98 – 108 mmol/L.

Bicarbonate: The recommended level is 22-30 mmol/L.

A deficiency or excess in the level of these electrolytes can negatively affect cell function and in turn impact the respiratory system, nervous system and critical organs.

Special Instructions – While a typical electrolyte test has no special instructions for a patient, if the levels of calcium and phosphorus are also being checked, an 8 hour fast (including only plain water) is advised.
