The A1c (glycohemoglobin) test provides a reliable method to measure and/or assess the average level of individual diabetes control over a defined time period.  The standard time period is 90 days.  But, some think 60 days is more appropriate, while thers say 120 days is better.  The User can select the time period of 0, 60, 90, or 120 days by menu selection.  The software will check the average BG Readings from the date of the A1c test going back o the User selected time period.

The results will give a good comparison of your meter readings to your doctor's A1c test.  Select the Date of your A1c test, and then enter the results of the A1c Test.
