Abstract

Glucometers offer a simple and rapid method of self-monitoring blood glucose levels and are widely used by diabetic clinics and patients. The accuracy of a glucometer depends on the meter's performance as well as the user's proficiency level. It is also important to regularly use and calibrate the meter it in order to maintain consistent readings. Since glucometers are considered clinically accurate if the result is within +/- 15 mg/dL of the results of the manufacturer's measurement procedure at glucose concentrations < 75 mg/dL, and within +/- 20% at glucose concentrations > or = 75 mg/dL. It is crucial to compare the meter's result with a lab test result at least once a year in order to maintain the reliability of the meter. Diabetes educators should have thorough knowledge of each meter and be aware of its accuracy so that he or she can properly and accurately educate diabetic patients.
