Insulin correction scale calculates rapid-acting insulin dose to bring elevated blood sugar to target. It's personalized to individual sensitivity.

Formula

Dose = (Actual BG - Target BG) / Correction factor
BG
BG value — Variable used in the calculation

Step-by-Step Guide

  1. 1Calculate correction factor: 1500/total daily insulin doses = mg/dL per unit
  2. 2Or use 1700 for more conservative dosing
  3. 3Dose = (Actual BG - Target BG) / Correction factor

Worked Examples

Input
BG 350, target 100, correction factor 50
Result
Correction dose = (350-100)/50 = 5 units
Plus meal insulin

Common Mistakes to Avoid

  • Using wrong total daily dose in calculation
  • Applying correction without accounting for meal carbs
