1. What is the Correction Factor?

The correction factor (also called insulin sensitivity factor) estimates how much 1 unit of rapid-acting insulin will lower your blood glucose. It's an essential component of insulin therapy for diabetes management.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( CF \) — Correction factor (mg/dL per unit)
• \( TDD \) — Total daily dose of insulin (units)

Explanation: The "1500 rule" is commonly used for regular insulin. For rapid-acting insulin analogs, some clinicians use the "1800 rule" instead.

3. Importance of Correction Factor

Details: Knowing your correction factor helps calculate insulin doses needed to correct high blood glucose levels while avoiding hypoglycemia.

4. Using the Calculator

Tips: Enter your total daily insulin dose (basal + bolus) in units. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Should I use 1500 or 1800 in the formula?
A: 1500 is typically used for regular insulin, while 1800 may be used for rapid-acting analogs like lispro, aspart, or glulisine.

Q2: How often should I recalculate my correction factor?
A: Recalculate whenever your total daily insulin dose changes significantly (by 10% or more).

Q3: Is this calculator suitable for children?
A: Yes, but pediatric patients may need individual adjustments under medical supervision.

Q4: What factors can affect my actual correction factor?
A: Physical activity, stress, illness, time of day, and insulin resistance can all affect insulin sensitivity.

Q5: Should I adjust my correction factor based on this calculation alone?
A: No, always consult with your healthcare provider before making changes to your insulin regimen.
