Sodium Concentration Correction for Hyperglycemia (Emmett 2013)(conventional or SI units)

 

Input
 

Measured plasma or serum sodium concentration		mEq/L mmol/L
Serum glucose		mg/dL mmol/L

 
Result
 
Important: Inputs must be complete to perform calculation.

 

Estimated (corrected) plasma sodium*		mEq/L
Decimal Precision   0 1 2 3

 

     
 
Include literature references: Yes   No

 

 

^*The estimated (corrected) plasma sodium is a rough estimate of how much the serum sodium concentration will rise as hyperglycemia is corrected.

 

 
Equations used
 

Estimated (corrected) plasma sodium* = Measured plasma or serum sodium concentration + (2 * (Serumglucose - 100) / 100)
