Causes a falsely low sodium concentration without a true change in total body sodium.  Commonly seen in DKA:  Hyperglycemia raises plasma osmolality. Water shifts from the intracellular to extracellular space. This dilutes serum sodium, creating apparent hyponatremia.  Corrected sodium calculation: Use tools like MDCALC, or apply this formula:  Add 1.6 mEq\/L to the measured sodium for every 100 mg\/dL increase in glucose above 100.  Clinical relevance:  Considering corrected sodium in DKA is crucial, as the lab value may not be reflective of actual sodium depletion. True severe hyponatremia can lead to complications like seizures  May require treatment with hypertonic saline.    References:  Fulop M. Acid\u2013base problems in diabetic ketoacidosis.
