01 - Meal's insulin - How does the calculation work ? [Top]

GluCalc calculates the insulin amount to be injected. It uses the correction factor or correction dose method.

Formula

Formula's parameters

1. Meal's insuline (MI) or insulin amount for the meal.
2. Ingested carbohydrates (IC), expressed in grams. 
3. Insulin amount (IA10), expressed in IU for 10 grams carbohydrates for a specific meal type.
   
4. Measuring Blood Glucose (MBG) measured before meal, expressed in selected unit.
   
5. Target Blood Glucose (TBG) or desired blood glucose value after the meal, expressed in selected unit.
   
6. Insulin sensivity factor (ISF) is a specific value for each meal and each diabetic patient. It allows to predict how many the blood glucose will be reduced – in selected unit - by injection of one insulin unit.

03 - Ratio IU/kg - How does the calculation work ? [Top]

The ratio IU/kg expresses the daily insulin amount per kilogram of body weight. It is calculated as following :

1. Insulin amount for all meals of the day. This amount is calculated for each meal considering a blood glucose value of 6.0 mmol/l or 108 mg/l or 1.1 g/l and a carbohydrate amount corresponding to the carbohydrates target set for the meal.
   
2. Daily basal insulin amount - this value is set by the Settings icon and initial set up menu.
   

The ratio IU/kg is calculated with the sum of these two insulin amounts divided by the body weight of the patient. 

04 - How to create a foods file and import it into GluCalc ? [Top]

Glucalc can import a food file in the form of an array. The columns of the array must be separated by a semicolon. The column order and the semicolon separator must be respected to make it work.

The example below shows the first row containing titles. The following rows contain data that will be imported.

Food group;Food;Carbohydrates;Quantity;Unit
Grains;White bread;50;100;g
Fruits;Apricot;10;100;g
