Formula & Mathematical Methodology: Corrected Sodium (Glucose) Formula

NaKatz = MeasuredNa + 0.016 × (GlucosemgdL − 100)
NaHillier = MeasuredNa + 0.024 × (GlucosemgdL − 100)
Na_Katz = Measured_Na + 0.016 × (Glucose_mg_dL − 100); Na_Hillier = Measured_Na + 0.024 × (Glucose_mg_dL − 100)
  • measuredSerumSodiumMeqL: Measured Serum Sodium Meq L (mEq/L)
  • serumGlucoseMgDl: Serum Glucose Mg Dl (mg/dL)

Rounding: Clinical scores round to statutory integer or decimal precision; physiological metrics round to 2 decimal places.

Worked Example: Clinical / Physiology Scenario: Corrected Sodium (Glucose)

Correct measured serum Na+ for elevated blood glucose above 100 mg/dL.

  1. Enter lab values, anthropometric measurements, or performance test metrics.
  2. Evaluate the reference equation: Na_Katz = Measured_Na + 0.016 × (Glucose_mg_dL − 100); Na_Hillier = Measured_Na + 0.024 × (Glucose_mg_dL − 100).
  3. Inspect the primary classification, supporting indices, and 3 SVG charts.
Result: Computes Corrected Sodium (Glucose) via Na_Katz = Measured_Na + 0.016 × (Glucose_mg_dL − 100); Na_Hillier = Measured_Na + 0.024 × (Glucose_mg_dL − 100).

Corrected Sodium for Hyperglycemia (Katz 1.6 & Hillier 2.4 Formula) Calculator: inputs, method, and how to read the result

Correct measured serum Na+ for elevated blood glucose above 100 mg/dL.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Measured Serum Sodium Meq L: Measured lab serum sodium (mEq/L).
  • Serum Glucose Mg Dl: Serum blood glucose level (mg/dL).

What the calculation includes

With the default values shown, Corrected Serum Sodium (Katz 1.6 Formula) is 135.2 mEq/L. The calculation follows Corrected Sodium (Glucose) Formula; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Measured Serum Sodium Meq L from 128 mEq/L to 141 mEq/L changes Corrected Serum Sodium (Katz 1.6 Formula) from 135.2 mEq/L to 148.2 mEq/L. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses peer-reviewed clinical and sports physiology formulas.
  • For educational and informational reference only; clinical scores do not replace physician judgment or laboratory reference ranges.

Scope: Global Clinical & Sports Science Consensus Check the assumptions and limitations against your situation before relying on the estimate.
