Clinical takeaway

Hyperglycaemia dilutes serum sodium.

When to use

Interpret sodium in patients with marked hyperglycaemia (e.g. DKA/HHS).

How it works

Corrected Na = measured Na + 1.6 × (glucose − 100)/100 (mg/dL); the 2.4 factor (Hillier) is often better at glucose > 400.

Key points

  • Hyperglycaemia dilutes serum sodium.
  • Use corrected sodium to judge true hypo-/hypernatraemia.
  • Reassess as glucose falls with treatment.

FAQ

Frequently asked questions

What are the limits and cautions when using Corrected Sodium for Hyperglycaemia?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Corrected Sodium for Hyperglycaemia upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Corrected Sodium for Hyperglycaemia calculated in practice? Can you show a worked example?
Inputs: Measured sodium 130 mmol/L, Glucose 600 mg/dL → Result: Corrected Na (×1.6) 138.0 mmol/L（Corrected Na (×2.4, Hillier): 142.0 mmol/L, Formula: Na + 1.6 (or 2.4) × (glucose − 100)/100, mg/dL）
