Dario Blood Glucose Monitoring System - Android Devices User Performance Study Report

LabStyle Innovations Ltd.102 enrolled

Overview

The purpose of this study is to evaluate the accuracy of the Dario Blood Glucose Monitoring System as compared to a reference method (Yellow Springs Instrument 2300 STAT Plus) and to evaluate the usability of the device when used by laypersons.

The objectives for this study are to evaluate the blood glucose level results obtained from the subject's fingertip using the Dario Blood Glucose Monitoring System paired with a reference device from one of three Android smart mobile device families as compared to the results from the Yellow Springs Instrument 2300 STAT Plus. The usability of the Dario Blood Glucose Monitoring System when paired with a reference device from one of three Android smart mobile device families and used by laypersons is also evaluated.

Outcomes

Primary Outcomes

Accuracy of Glucose Concentrations (%)

Accuracy acceptability is defined as follows: Ninety-five percent (95%) of the individual glucose results shall fall within +/-15 mg/dL of the results of the Dario's measurement at glucose concentrations \< 75 mg/dL and within +/- 20% at glucose concentrations greater than or equal to 75 mg/dL. The accuracy of the Dario Blood Glucose Monitoring System when used with Android operating system smart mobile devices was assessed against the Yellow Springs Instrument 2300 STAT Plus.
