A relative dilutional hyponatremia can occur in the presence of serum hyperglycemia. Hyperglycemia causes osmotic shifts from the intracellular to the extracellular spaces in the body. The original correction factor of 1.6 mEq/L for every 100 mg/dL increase in serum glucose was established by Katz (1973). Hillier et al (1999) challenged the original factor and proposes a factor of 2.4 mEq/L as a more accurate alternative.
.Summary
There are two proposed ways of evaluating the correction factor for hyperglycemia-induced hyponatremia.
Corrected Sodium (Katz, 1973) = Measured sodium + 0.016 * (Serum glucose - 100)
Corrected Sodium (Hillier, 1999) = Measured sodium + 0.024 * (Serum glucose - 100)
Note: Serum glucose must be in mg/dL
