What this calculator does
Calculates Sodium Correction for Hyperglycemia (Katz) using the formula verified against the cited source.
What your result means
An estimate from the inputs you enter, within the scope stated below — not advice.
Formula
Corrected Na = measured Na + 1.6 × ((glucose − 100) ÷ 100)
The step-by-step working for your own numbers appears with the result above and in the PDF report.
Frequently asked questions
Symbols and assumptions
- Inputs
- The values entered in the fields above
- • Katz hyperglycemia adjustment: corrected sodium=measured sodium+1.6×[(glucose mg/dL−100)/100], in mEq/L. With glucose mmol/L, convert to mg/dL (approximately ×18) first.
Sources and review

- • Identify Katz 1.6 specifically; other empirically studied factors differ, especially at marked hyperglycemia. This is an estimated sodium after glucose normalization, not a prescription for saline or an instruction to correct sodium by that amount.
Important limitation
This is an educational estimate based only on the values and formula shown. Verify current rates, rules, units, and professional standards before relying on the result. It is not personalized financial or investment advice.
