System Accuracy Evaluation of 6 CE-marked Blood Glucose Monitoring System Following ISO 15197:2013

System Accuracy Evaluation of Accu-Chek Aviva Nano (Roche Diagnostics), Accu-Chek Performa Nano (Roche Diagnostics), FreeStyle Lite (Abbott Diabetes Care), OneTouch Verio IQ (LifeScan), Contour Next Link 2.4 (Bayer Consumer Care), One Additional CE-marked Blood Glucose Monitoring System Following ISO 15197:2013

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.

Inclusion Criteria:

• Male or female, with type 1 diabetes, type 2 diabetes or no diabetes
