The Sodium Correction for Hyperglycemia calculator adjusts the measured serum sodium levels to account for hyperglycemia. Hyperglycemia causes a dilutional hyponatremia due to the osmotic effect of glucose, pulling water from intracellular to extracellular compartments. This correction is vital for accurately assessing a patient’s sodium status in the presence of elevated blood glucose levels.
