Abstract

Background: Blood Glucose Monitoring Systems (BGMS) are an important tool in the management of diabetes. The gold standard in measuring the accuracy of BGMS in the self-testing of diabetes mellitus is known as the ISO 15197:2013. The level of accuracy of the BGMS results in a personâ�?�?s ability to regulate their blood sugar levels. According to ISO 15197:2013, system accuracy performance criteria is defined as 95% of the BGMS results falling within �?±15 mg/dL of the reference analyzer results with glucose concentrations less than 100 mg/dL. For samples with glucose concentrations â�?¥100 mg/dL, 95% of the BGMS results need to be within 15% of the reference analyzer results. Furthermore 99% of all results are required to be in the A and B zones of the Consensus Error Grid. Purpose: The objective of this study is to demonstrate whether the ARKRAY GLUCOCARD 01 aligns with the newly introduced BGMS self-monitoring performance requirements. Methods: Two lots of ARKRAY GLUCOCARD 01 blood glucose test strips were evaluated for performance and bias comparison (N=120 data points). The samples were collected from the fingertip of confirmed diabetics by trained personnel in September 2014 at the ARKRAY Factory, Inc. Reference values were obtained using the YSI Model 2300 Analyzer. The data was analyzed using the minimum system accuracy performance criteria published in the ISO 15197:2013. Results: The results showed that 100% of the <100 mg/dL samples (n=8/8) were �?± 15 mg/dL thus exceeding the 95% accuracy criteria. 97.3% of the â�?¥100 mg/dL samples (n=109/112) fell within the pre- determined 15%, which surpassed the 95% performance criteria. All data were within the A and B zones of the Consensus Error Grid. The overall bias was -0.1% demonstrating a strong agreement between the GLUCOCARD 01 and the YSI reference analyzer, which is considered the gold standard glucose assay for BGMS studies. The correlation coefficient (r) =0.98 demonstrates a strong linear relationship between the YSI and meter result. Conclusion: The data acquired on the ARKRAY GLUCOCARD 01 met the ISO 15197:2013 system accuracy performance criteria, the most stringent BGMS requirement in the self-monitoring of diabetes mellitus.
