Corrected Sodium Calculator (Hyperglycaemia)
True sodium behind the dilution of high glucose — the Katz/Hillier correction DKA management leans on.
Glucose drags water into the vessels and dilutes sodium — the 128 here 'corrects' to ~133.6 (Katz), changing the entire hyponatraemia workup. Hillier's experimental data suggested 2.4 fits better above ~400 mg/dL, which is why both are shown. As DKA treatment drops the glucose, watch the *corrected* trend: measured sodium will rise by design.

About Corrected Sodium Calculator (Hyperglycaemia)
Glucose drags water into the vessels and dilutes sodium — the 128 here 'corrects' to ~133.6 (Katz), changing the entire hyponatraemia workup. It applies corrected Na = measured + 1.6 (Katz) or 2.4 (Hillier) × (glucose − 100)/100. Use the Corrected Sodium Calculator (Hyperglycaemia) to get an instant, clearly-explained result with the working shown step by step — free, private and with the source method cited.

Frequently asked questions
How does the Corrected Sodium Calculator (Hyperglycaemia) work?+
Glucose drags water into the vessels and dilutes sodium — the 128 here 'corrects' to ~133.6 (Katz), changing the entire hyponatraemia workup. The calculation uses the formula: corrected Na = measured + 1.6 (Katz) or 2.4 (Hillier) × (glucose − 100)/100. Everything runs instantly in your browser as you type — your inputs are never uploaded.
Is the Corrected Sodium Calculator (Hyperglycaemia) accurate, and what is it based on?+
The method is traceable to authoritative sources, including Katz MA, NEJM 1973; Hillier TA et al., Am J Med 1999. Results are estimates — individual variation always applies, so treat the output as a well-grounded starting point.
Is the Corrected Sodium Calculator (Hyperglycaemia) free and private?+
Yes. It's completely free with no sign-up, and all computation happens locally in your browser, so none of your health data ever leaves your device.
Can I use this for medical decisions?+
This is a reference aid for healthcare professionals and must be independently verified. It is not for self-diagnosis or self-medication.
What can I use the Corrected Sodium Calculator (Hyperglycaemia) for?+
It's commonly used for corrected sodium, sodium hyperglycemia, dka sodium. True sodium behind the dilution of high glucose — the Katz/Hillier correction DKA management leans on.
