    The principal investigators of the study request that you use the official version of the modified score here.

    Sodium Correction for Hyperglycemia

    Calculates the actual sodium level in patients with hyperglycemia.
    Pearls/Pitfalls

    Hyperglycemia causes osmotic shifts of water from the intracellular to the extracellular space, causing a relative dilutional hyponatremia. The classic correction factor of 1.6 mEq/L for every 100 mg/dL increase in serum glucose was challenged by a paper by Hillier et al in 1999, and sometimes their factor of 2.4 mEq/L is used.
