The Diabetes Personal Calculator provides the functionality of:

  • Selecting food items from a generic food database
  • Modifying serving or weight to get the corresponding carbs for the food
  • Calculating a bolus insulin dose based on your blood glucose reading and correction factor
  • Calculating a pre-meal insulin dose based on your blood glucose reading and correction factor (optional), and the amount of carbohydrates in your meal or snack based on your carbs/insulin ratio

The Diabetes Personal Calculator calculates a suggested pre-meal insulin dose of fast or rapid acting insulin, based on your current pre-meal blood glucose reading, your target blood glucose, your Correction Factor, the carbohydrate value of the meal or snack you are about to consume, and your Carbs/Insulin Ratio, using the formula provided in the Calculations section below.

The Diabetes Personal Calculator will also calculate a bolus insulin dose of fast or rapid acting insulin based on your Correction Factor.

The Diabetes Personal Calculator allows you to look up the carbohydrate values of common foods from its built in generic food database.

The Diabetes Personal Calculator is a tool designed to give you convenience. It must only be used as a guide, and upon advice and consultation with your physician.

Calculations

The Diabetes Personal Calculator is implemented with the following formula based on your current pre-meal blood glucose reading, your target blood glucose, your Correction Factor, the carbohydrate value of the meal or snack you are about to consume, and your Carbs/Insulin Ratio, to calculate your suggested fast, or rapid acting, pre-meal insulin dose:

(Current BG – Target BG) / Correction Factor
+  Carbs / (Carbs/Insulin Ratio)
= Suggested Insulin

Correction Factor
The Correction Factor is a formula to calculate how much insulin is required to bring down a high blood sugar into the target range, or to bring up a low blood sugar into the target range.
If you are measuring your blood glucose in mg/dl this formula is calculated by dividing your total daily insulin dose into either 1500, if you use one of the fast acting insulins, or 1800, if you use one of the newer rapid acting insulins.
If you are measuring your blood glucose in mmol/l this formula is calculated by dividing your total daily insulin dose into either 83, if you use one of the fast acting insulins, or 100, if you use one of the newer rapid acting insulins.
The Correction Factor is also used by the Diabetes Personal Calculator to calculate a bolus insulin dose.

Carbs/Insulin Ratio
This is also known as your Carbohydrate Factor and is a figure that is calculated by dividing the carbs in your meal by the number of units of insulin necessary to keep your blood glucose in the normal range after your meal is consumed. This number, when divided by the number of carbs contained in a meal, will give the number of units of insulin necessary to inject. Because this number can sometimes vary throughout the day, we have provided the opportunity for you to enter up to six different ratios, for breakfast, mid morning snack, lunch, mid afternoon snack, dinner, and evening snack. You can also use the mid morning snack, mid afternoon snack and evening snack options to calculate and record any bolus injections that may be necessary from time to time.

Data Persistence

The data you enter for each meal will be cached until you exit the App. To be able to save all your data to the database and to view as reports and to send email, please purchase

The Diabetes Personal Manager
An all-in-one insulin calculator, carbohydrate database, favorites database, and diary.

Personal Settings

The following must be entered into “Settings” under the supervision of your physician:

  1. The unit of measurement your blood glucose monitor uses either mg/dl or mmol/l.
  2. Your target blood glucose measurement.
  3. Your Correction Factor.
  4. Your Carbohydrate to Insulin Ratio(s), or Carbohydrate Factor(s) for each meal and snack that you consume during the day.

Generic Food List

The carbohydrate figures, serving sizes and weights programmed into the Diabetes Personal Calculator by the authors under the list of “Generic Foods”, have been taken from data obtained from the National Agricultural Library, Agricultural Research Service, U. S. Department of Agriculture, USDA National Nutrient Database for Standard Reference, Release 22.

Important

If you are in any doubt about the insulin dose suggested by the Diabetes Personal Calculator, or regarding any other matter concerning your diabetes management, your physician’s advice must always supercede any information provided by the Diabetes Personal Calculator.

Disclaimer

The authors of this Application are not engaged in rendering medical advice or recommendation. The Diabetes Personal Calculator is designed for use only as a guide. As instructed above, and on the initial warning pop up, the user must enter data into the ‘Personal Settings’ section under the supervision of their physician. The authors of the Diabetes Personal Calculator cannot accept any responsibility for such data being entered incorrectly. The Diabetes Personal Calculator cannot take into account all the many variables that determine blood glucose outcomes, and therefore returning blood glucose to target cannot be guaranteed. The authors, therefore, assume no responsibility in any way, shape, or form, for any adverse health conditions, including hypoglycemic or hyperglycemic episodes, that a user may experience after using the Diabetes Personal Calculator.
