How often do you use control solution to check your blood glucose meter?

Poll dates: July 28 - August 4, 2002
Total Votes: 544

Over half of the respondents to this poll either never use or rarely use control solution to check their home blood glucose meters. Checking meters is extremely important because you are making a lot of decisions based on obtained results. In addition, we often get questions relating to discrepancies between home test results and hemoglobin A1c. Such differences may be the result of a poorly functioning meter or "bad strips."

The calibration code, strip, or chip merely sets the meter for the batch of strips being used. Control solutions measure the accuracy of the strips. Regulations require that meters used in hospitals, doctors offices, etc. be checked daily with both a check strip as well as High and Low control solutions. This assures correct readings.

If you are not currently routinely checking every vial of strips for accuracy with control solution, you should rethink this practice, especially if you have them shipped to your home. Temperature extremes and humidity can greatly affect accuracy. Your life (or your child's) may depend on it.

The results of this poll are essentially the same as the results from the two previous times we ran this poll:

Answer    July 2002 July 2001 July 1999
Every new vial    18% 16% 18%
More than once a month    1% 3% 2%
About once a month    8% 8% 10%
Couple times a year    20% 22% 21%
Once, with new meter    13% 15% 10%
Never, or almost never    36% 32% 33%
Other    1% 2% 2%
