Corrected Sodium (Hyperglycemia)

Adjust measured serum sodium for the effect of hyperglycemia.

Measured sodium mEq/LGlucose mg/dL

Formula: Corrected Na = Measured Na + 1.6 x [(Glucose - 100) / 100]
Clinical context: Corrected sodium guides true sodium deficit assessment in hyperglycemia.
Limitations: Some sources use 2.4 mEq/L per 100 mg/dL glucose for severe hyperglycemia.
