Hillier Hyperglycemia-Corrected Sodium calculator

Enter the published formula inputs below to calculate and interpret this score.

Clinical inputs

Measured serum sodium (mmol/L)

Serum glucose (mg/dL)

Use only for hyperglycemia with glucose ≥100 mg/dL. The Hillier correction uses the experimentally observed overall average of 2.4 mmol/L sodium per 100 mg/dL glucose above 100 mg/dL.

Result

Complete all required inputs to calculate the score.

Formula inputs

Measured serum sodium (mmol/L)Accepted range: 50 to 250
Serum glucose (mg/dL)Accepted range: 100 to 3000
