About Correction Bolus
- Formula: Correction = (Current glucose − Target glucose) / ISF
- ISF: Insulin Sensitivity Factor — how much 1 unit of insulin lowers your blood glucose (in mmol/L).
- Note: This does not account for insulin on board (IOB). If you recently bolused, the actual correction needed may be less.
