Accuracy and User Performance of a New Blood Glucose Monitoring System

Area of Science:

• Medical Devices
• Diabetes Technology
• Clinical Diagnostics

Background:

• Self-monitoring of blood glucose (BG) is crucial for diabetes management.
• Accurate BG monitoring informs therapy adjustments and glycemic target achievement.
• Evaluating new blood glucose monitoring systems (BGMS) against established standards is essential.

Purpose of the Study:

• To assess the accuracy and user performance (UP) of the CONTOUR®PLUS ELITE BGMS.
• To evaluate the BGMS against International Organization for Standardization (ISO) 15197:2013 criteria and more stringent benchmarks.
• To determine the system's suitability for people with diabetes (PWD).

Main Methods:

• Laboratory Study 1: 100 PWD capillary fingertip blood samples tested with the BGMS.
• Clinical Study 2: 130 PWD BG measurements compared against YSI analyzer (finger, palm, venous samples).
• User performance assessed via questionnaire; test strip lots evaluated.

Main Results:

• 100% accuracy met ISO criteria; 99.8% met more stringent criteria (±10 mg/dL or ±10%).
• Error grid analysis showed 100% of results in Zone A.
• >98% subject and 100% staff performance met ISO criteria; >96% found the system easy to use.

Conclusions:

• The CONTOUR®PLUS ELITE BGMS surpasses minimum ISO 15197:2013 accuracy and UP standards.
• The system also meets more stringent accuracy criteria.
• This BGMS is a valuable tool for managing glycemic control in people with diabetes.
