The objective of this study is the evaluation of system accuracy following ISO 15197:2013 (E), 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. In this study, system accuracy evaluation will be performed with CE-marked BGMS (BGMS = Blood Glucose Monitoring System) common among insulin pump users - Accu-Chek Aviva Nano and Accu-Chek Performa Nano (Roche Diagnostics), FreeStyle Lite (Abbott Diabetes Care), OneTouch Verio IQ (LifeScan) Contour Next Link 2.4 (Bayer Healthcare Diabetes Care) and Accu-Chek Mobile with three different reagent system lots for each BGMS.
The study will be performed in 2 parts. Each part will comprise testing of 3 BGMS.

| System accuracy criteria (see description) | System accuracy criteria Following 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. Applying ISO 15197:2003 accuracy criteria: 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 < 75 mg/dl (4.2 mmol/l) or within ± 20 % at glucose concentrations ≥ 75 mg/dl (4.2 mmol/l). | For each subject, the experimental phase has an expected duration of up to 6 hours |
