Insulin Dose Analysis

Insulin Dose Formula

Total Dose = (Carbs / Carb Ratio) + ((Current BG – Target BG) / Correction Factor)

The total insulin dose is calculated by determining carbs coverage (carbs divided by carb ratio) plus correction dose (difference between current and target BG divided by correction factor).
