Electrolytes are present in the human body, and the balance of the electrolytes in our bodies is essential for normal function of our cells and our organs. Common electrolytes that are measured by doctors with blood testing include sodium (Na), potassium (K), chloride(Cl), and bicarbonate.
An electrolyte test can help determine whether there’s an electrolyte imbalance in the body.
A Normal blood sodium level is 135 – 145 milliEquivalents/liter (mEq/L), or in international units, 135 – 145 millimoles/liter (mmol/L). The normal blood potassium level is 3.5 – 5.0 milliEquivalents/liter (mEq/L), or in international units, 3.5 – 5.0 millimoles/liter (mmol/L). The normal serum range for chloride is 98 – 108 mmol/L. The normal serum range for bicarbonate is 22-30 mmol/L.
