Basal Rate Estimator - Detailed INSTRUCTIONS
Use of the Basal Rate Estimator is best accomplished by profiling
fasting basal requirements and blood sugars levels
over an 8 to 10 hour period.
Before trying to use this tool, please read:
Click on the illustration to see a full size example of the Basal
The Basal Rate Estimator is divided into 5 areas. Data entered into
each area will increase the detail of the information calculated and will be
returned to the browser as a graphic plot of the test period.
If at any time, an incorrect data entry is made, when the SUBMIT
button is pushed a WARNING MESSAGE will appear in the data entry
boxes describing the nature of the problem. Click BACK on your
browser and correct the problem.
Time and Blood Sugar readings.
Enter the time of each reading and the Blood Sugar value for an 8 to 10 hour
You may SUBMITthe data now to plot a graph of Blood Sugar levels for
the test period, or continue.
- Enter the Basal Rates that you use NOW. Include the basal rate
for the 2 to 4 hour period prior to the beginning of the test interval. If
you don't actually have a basal rate starting in that time frame, then use a
time 2 hours prior to the start of the test period and enter the basal rate that
normally runs at that time.
You may SUBMIT the data now to plot both Blood Sugar levels and Basal
Rates for the test period, or continue.
Enter your Blood Sugar to Insulin ratio. If you are unsure of or need to measure your Blood Sugar to
Insulin ratio, see HOWTO measure Blood Sugar to Insulin
Click the button for the type of insulin you use. If you use a mix of
lispro (Humalog) and a regular insulin, click the button for
- Enter the NEW Basal Rates you would like to try. The first
entry must have the same Time as the entry in BOX #2. You may change any of the
Basal Rates and any of the other Times.
- SUBMIT the data now to obtain a plot of the Blood Sugar levels
and Basal Rates during the test period superimposed with the NEW
Basal Rates and the ESTIMATED new Blood Sugar levels.

to see the complete example.
The plot is divided into 2 areas. The upper portion is a plot of Blood
Sugar values over the test period. The data will not be shown beyond 10
hours but it will be used in the calculation of the plot end points and
the estimated blood sugar values. Blood Sugar levels are plotted in
and the estimated Blood Sugar levels are plotted
The lower portion of the plot shows the current Basal Rate and the proposed NEW
Basal Rate. The current Basal Rate is shown as a SOLID
RED area. DECREASE in
estimated Basal Rate is depicted as the ABSENCE of color
with the original Basal Rate outlined in
RED. INCREASE in
estimated Basal Rate are depicted as a SOLID GREEN area.
