Researchers have found that practice, at least in the area of blood glucose monitoring, does not make perfect. Fresh from training by a diabetes educator, people start off getting accurate results. But as time goes by, people begin to get sloppy. Accuracy usually decreases over time.

Take your meter with you for checkups, and ask your health care provider to observe your technique from time to time. Or measure your blood glucose level with your own meter when your blood is drawn for laboratory glucose tests. Record your results. The two readings are best compared when you are fasting. When your lab-tested blood results are available, compare the numbers.

-   Make sure that you are comparing plasma blood readings (not whole blood) from your meter to your lab results.

 

-   If your result was off by more than 5-10%, go over your technique with your diabetes educator or provider. If he or she can’t find any problems with your technique, it’s time to suspect that something may be wrong with your meter.

Diabetic meters measure the amount of glucose in a drop of blood. The blood sample -- usually taken from your fingertip -- is placed on a disposable test strip that is coated with chemicals that react with glucose inserted into the meter. Inside the meter, the test strip is zapped with an electrical current and your blood sugar level is displayed. Refer to the instruction manual that came with your meter for detailed instructions on how to use it properly.
