Frequently Asked Questions

Find Quick Answers

What is the JDRF Calculator used for?

The JDRF Calculator helps people with diabetes calculate their insulin dosage needs based on carbohydrate intake, current blood glucose levels, and personal insulin sensitivity factors.

How accurate is the insulin dose calculation?

The calculator provides estimates based on standard diabetes management formulas. Always consult with your healthcare provider for personalized medical advice and dosage adjustments.

What is insulin-to-carb ratio?

Insulin-to-carb ratio (ICR) is the number of grams of carbohydrates covered by 1 unit of rapid-acting insulin. For example, a 1:15 ratio means 1 unit covers 15g of carbs.

What is correction factor?

Correction factor (also called insulin sensitivity factor) is the amount blood glucose decreases per unit of insulin. For example, 1:50 means 1 unit lowers blood glucose by 50 mg/dL.

Should I subtract active insulin?

Yes, if you have active insulin from a previous dose, you should subtract it from the calculated dose to avoid insulin stacking and potential hypoglycemia.
