System Accuracy:
Diabetes experts have suggested that glucose meters should agree within 15 mg/dL of a laboratory method when the glucose concentration is lower than 75 mg/dL, and within 20% of a laboratory method when the glucose concentration is 75 mg/dL or higher. Samples from 100 patients were tested using both the OneTouch Verio IQ® System and the YSI 2300 Glucose Analyzer laboratory instrument.
System Accuracy Results for Glucose Concentrations <75 mg/dL:
Percent (and number) of meter results that match the laboratory test
System Accuracy Results for Glucose Concentrations >75 mg/dL:
Percent (and number) of meter results that match the laboratory test
System Accuracy Results across the entire Glucose Range:
Percent (and number) of meter results that match the laboratory test
Therefore, 100% of the total results obtained with the OneTouch Verio IQ® System achieved the goal suggested by the diabetes experts.
Regression Statistics:
Samples were tested in duplicate on each of three test strip lots. Results indicate that the OneTouch Verio IQ® System compares well with a laboratory method.
Precision:
Within Run Precision (300 Venous Blood Tests)
Results show that the greatest variability observed between test strips when tested with blood is 2.86% or less.
