Evaluation of Blood Glucose Monitoring Systems

Evaluation of Blood Glucose Meter Systems - Contour® NEXT LINK Study

The purpose of this study was to evaluate the performance of a Bayer Blood Glucose Monitoring System (BGMS) and two additional Blood Glucose Monitoring Systems (BGMS) from other companies. All meter BG results were compared with plasma results obtained with a reference laboratory glucose method (YSI Glucose Analyzer).

Detailed Description

The purpose of this study was to evaluate the performance of a Bayer Blood Glucose Monitoring System (BGMS) and two additional Blood Glucose Monitoring Systems (BGMS) from other companies. All meter BG results were compared with plasma results obtained with a reference laboratory glucose method (YSI Glucose Analyzer). Performance of the three systems was evaluated across the glucose range of the BGMSs using capillary blood. All testing and lancing was performed by study staff and some samples were tested from subject fingertips. Additionally, some blood samples were glycolyzed to lower the glucose concentration levels and glucose solution was added to other samples to raise glucose concentration levels.

Intervention / Treatment

Experimental: Subjects with and without Diabetes; All testing and lancing were performed by the study staff; Subjects with and without Diabetes did not perform any lancing or self-testing in this study. Study Staff lanced the fingers of subjects and tested the blood samples using three Blood Glucose Monitoring Systems (BGMS): Contour® NEXT LINK BGMS; OneTouch® UltraLink® BGMS; Nova Max Link® BGMS.

Device: Contour® NEXT LINK BGMS; Study staff performed Blood Glucose (BG) tests with capillary fingerstick blood collected from subjects with and without diabetes (up to 10% of subjects without diabetes were included). Performance of Contour® NEXT LINK BGMS was evaluated across the glucose range of the BGMSs. All meter BG results were compared with capillary plasma results obtained with a reference laboratory glucose method (YSI Glucose Analyzer).; Device: OneTouch® UltraLink® BGMS; Study staff performed Blood Glucose (BG) tests with capillary fingerstick blood collected from subjects with and without diabetes (up to 10% of subjects without diabetes were included). Performance of OneTouch® UltraLink® BGMS was evaluated across the glucose range of the BGMSs. All meter BG results were compared with capillary plasma results obtained with a reference laboratory glucose method (YSI Glucose Analyzer).; Device: Nova Max Link® BGMS; Study staff performed Blood Glucose (BG) tests with capillary fingerstick blood collected from subjects with and without diabetes (up to 10% of subjects without diabetes were included). Performance of Nova Max Link® BGMS was evaluated across the glucose range of the BGMSs. All meter BG results were compared with capillary plasma results obtained with a reference laboratory glucose method (YSI Glucose Analyzer).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
MARD (Mean Absolute Relative Difference Between BGMS Results and Reference Method Results) Across the Overall Tested Glucose Range	Using the overall Blood Glucose (BG) range (34 to 561 mg/dL according to YSI subject plasma results), the Mean Absolute Relative Differences (MARD) between the BGM System readings and the YSI plasma results (BG reference) were compared. MARD is calculated from the sum of all |(BG meter)-(BG reference)|/(BG reference) assessments, divided by the number of assessments, then multiplied by 100(%). Each evaluable sample was tested on all 3 BGMS, thus the same number of BG test results was analyzed for each BGMS intervention. Lower MARD value indicates smaller difference between meter value and the reference value. Higher MARD value indicates larger difference between meter value and the reference value.	8 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
MARD (Mean Absolute Relative Difference Between BGMS Results and Reference Method Results) in the Low Glucose Range (<=80 mg/dL)	Using fresh and glycolyzed samples with YSI plasma Blood Glucose (BG) ≤80 mg/dL, the Mean Absolute Relative Differences (MARD) between the BGM System readings and the YSI subject plasma results (BG reference) were compared. MARD is calculated from the sum of all |(BG meter)-(BG reference)|/(BG reference) assessments, divided by the number of assessments, then multiplied by 100(%). Each evaluable sample was tested on all 3 BGMS, thus the same number of BG test results was analyzed for each BGMS intervention. Lower MARD value indicates smaller difference between meter value and the reference value. Higher MARD value indicates larger difference between meter value and the reference value.	8 hours
MARD (Mean Absolute Relative Difference Between BGMS Results and Reference Method Results) in the High Glucose Range (>180 mg/dL)	Using samples with YSI plasma Blood Glucose (BG) >180 mg/dL, the Mean Absolute Relative Differences (MARD) between the BGM System readings and the YSI subject plasma results (BG reference) were compared. MARD is calculated from the sum of all |(BG meter)-(BG reference)|/(BG reference) assessments, divided by the number of assessments, then multiplied by 100(%). Each evaluable sample was tested on all 3 BGMS, thus the same number of BG test results was analyzed for each BGMS intervention. Lower MARD value indicates smaller difference between meter value and the reference value. Higher MARD value indicates larger difference between meter value and the reference value.	8 hours
