NOTE
• If data are not available to calculate averages, the No Data Available screen is displayed.
• Standard deviation measures how much the blood glucose test results are scattered around the
blood glucose average. A low standard deviation means the blood glucose test results are tightly
clustered around the blood glucose average; a high standard deviation means the blood glucose test
results are widely scattered around the blood glucose average.
• Calculations do not include control results, HI values, or LO values.
