Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Measured sodium | 130 mmol/L |
|---|---|
| Glucose | 600 mg/dL |
→Corrected Na (×1.6)138.0mmol/L
- Corrected Na (×2.4, Hillier)：142.0 mmol/L
- Formula：Na + 1.6 (or 2.4) × (glucose − 100)/100, mg/dL
Common questions
What is Corrected Sodium for Hyperglycaemia?
Correct measured sodium for hyperglycaemia to reveal the true sodium status.
How is Corrected Sodium for Hyperglycaemia calculated? What is the core formula?
Corrected Na = measured Na + 1.6 × (glucose − 100)/100 (mg/dL); the 2.4 factor (Hillier) is often better at glucose > 400.
When is Corrected Sodium for Hyperglycaemia used?
Interpret sodium in patients with marked hyperglycaemia (e.g. DKA/HHS).
What are the key clinical points for Corrected Sodium for Hyperglycaemia?
Hyperglycaemia dilutes serum sodium. Use corrected sodium to judge true hypo-/hypernatraemia. Reassess as glucose falls with treatment.
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.
How is Corrected Sodium for Hyperglycaemia calculated in practice? Can you show a worked example?
