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

Input

Measured plasma or serum sodium concentration

Glucose

Result

Important: Inputs must be complete to perform calculation.

Estimated (corrected) plasma sodium^*

Decimal Precision

Data action

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 * (Glucose - 100) / 100)
