Useful Definitions

Carb Factor (I:C) = the insulin to carb ratio

Correction Factor (ISF) = sometimes called an insulin sensitivity factor

Rel. Ins. Sensitivity (IS) = your sensitivity to insulin compared to an average of 100%. (< 100% = less sensitive, > 100% = more sensitive)

TDD = total insulin used per day

Avg BG = avg meter BG for 14 days or more (over 40 BG tests)

improved TDD (iTDD) = the TDD with correction boluses, resulting in a higher (usually) iTDD
