Electrolytes are the minerals that keep your nerves, muscles and fluid balance working. This panel checks sodium, potassium, chloride and bicarbonate.
| Measure | Range |
|---|---|
| Sodium (Na) | 135–145 mmol/L |
| Potassium (K) | 3.5–5.0 mmol/L |
| Chloride (Cl) | 98–107 mmol/L |
| Bicarbonate (HCO₃) | 22–29 mmol/L |
Potassium keeps the heart and muscles working. Both high and low levels can disturb the heart rhythm, so abnormal results are taken seriously.
Common causes include certain medicines (diuretics), excess water intake, and hormonal or kidney conditions. Symptoms range from none to confusion; the cause guides treatment.
