Conditions
Brief summary
The objective of this study is the evaluation of system accuracy based on EN ISO 15197:2015 (ISO 15197:2013), clause 6.3 in which accuracy requirements and applicable test procedures for blood glucose monitoring systems intended for self-monitoring of blood glucose by patients are stipulated. ISO 15197:20132 was harmonized with the regulations of the European Union as EN ISO 15197:2015. This harmonization had no impact on the requirements and procedu¬res in ISO 15197:2013; changes were made to the foreword and an informative annex. In this study, system accuracy evaluation will be performed for OneTouch® Verio Flex (LifeScan Europe) on behalf of LifeScan Scotland Limited (customer) with three different reagent system lots.
Interventions
Measurement procedure * Subjects will be asked to wash and dry their hands before the measurements. * The measurement procedure for each reagent system lot of a BGMS will be as follows: * Study personnel will collect a capillary blood sample from the subject's fingertip by skin puncture. * Duplicate measurements on the sample will be consecutively performed with 2 test meters using reagent system units from the same vial / package. * Capillary blood for measurements with all 3 test strip lots and for both comparison measurements will be taken from the same finger puncture. * The sample will be applied to the reagent system units following specifications in the manufacturer's labelling.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| System accuracy criteria | For each subject, the experimental phase has an expected duration of up to 6 hours | Based on EN ISO 15197:2015 (ISO 15197:2013) (E), the BGMS shall meet both of the following criteria: Criterion A: 95 % of the measured glucose values shall fall within either ± 15 mg/dl (0.83 mmol/l) of the average comparison measurement result at glucose concentrations \< 100 mg/dl (5.55 mmol/l) or within ± 15 % at glucose concentrations ≥ 100 mg/dl (5.55 mmol/l). Each lot shall pass acceptability criterion A. Criterion B: 99 % of individual glucose measured values shall fall within zones A and B of the Consensus Error Grid (CEG) for type 1 diabetes. |
