All blood glucose meters on the market are generally accurate, according to Mayo Clinic. However, the way the user stores and uses the meter has the potential to affect its accuracy. Factors to consider include the cost of the meter and strips along with the ease of use.
To check the accuracy of a meter, the U.S. Food and Drug Administration recommends using the control solutions each time the owner opens a new box of test strips. The meter reading should match the value the manufacturer prints on the vial. He should also note any errors on the device as it does its normal electronic testing each time he powers on the device. He can also test for accuracy by comparing the meterﾒs reading against those from his doctorﾒs laboratory.
