Corrected Sodium Calculator
Calculate corrected sodium levels for hyperglycemia using the Katz formula and correct for pseudohyponatremia.

Lab Values
Normal: 135-145 mEq/L
Pseudohyponatremia (Optional)
For hyperlipidemia correction
Normal: 6-8 g/dL
Corrected Sodium (Katz Formula)
137.2 mEq/L
Normal
Interpretation
Corrected sodium within normal range (135-145 mEq/L)
Sodium Correction Formulas
For Hyperglycemia
Traditional (1.6): Na + 1.6 × [(Glucose - 100) / 100]
Katz (2.4): Na + 2.4 × [(Glucose - 100) / 100]
Clinical Pearls
- Use 2.4 factor for glucose >400 mg/dL
- Pseudohyponatremia is a lab artifact
- True sodium requires direct measurement
- Consider osmolar gap in complex cases
