What does the term ICR stand for in insulin therapy?

• A. Insulin-to-Carbohydrate Ratio; used to adjust prandial insulin around meals.
• B. Insulin-Glucose Ratio.
• C. Insulin-Concentration Ratio.
• D. Insulin-Correcton Ratio.

Answer: (A)

Meal-time insulin dosing hinges on the insulin-to-carbohydrate ratio, which tells you how many units of rapid-acting insulin are needed to cover a given amount of carbohydrates in a meal. This ratio is individualized and used to calculate the prandial insulin dose around meals. For example, if your ICR is 1 unit per 10 g of carbohydrate, a meal with 50 g carbs would require about 5 units of rapid-acting insulin, adjusted for current blood glucose and activity level. Clinicians might estimate the ratio using practical rules (such as 500 divided by total daily insulin dose) and then patients fine-tune based on glucose responses. Other terms listed aren’t standard for meal dosing—Insulin-Glucose Ratio, Insulin-Concentration Ratio, and a misspelled Insulin-Correcton Ratio do not describe the mechanism of matching insulin to carbohydrate.
