The primary objective of this study is to identify device characteristics, components, or subsystems that manifest as screening score bias in SCOUT DS.
The study will switch subsystems between devices and if the bias differs by more than 3.5 Diabetes Risk Score units compared to the baseline score, we would conclude that the bias was contained within that particular subsystem

In the process of calibrating multiple SCOUT DS units, consistent inter-device score differences were found. These differences could create a bias in the measurement of Diabetes Risk scores (DRS) in human subjects. This study is intended to examine two of the various subsystems of the SCOUT DS to determine whether either of them might be capable of introducing bias into the measurements, with the ultimate aim of eliminating inter-device measurement variation.
The testing of human subjects in this trial is necessary to determine whether variability in the performance of these device subsystems actually affect DRS scores in a real world setting.
The trial will be a prospective, single site, investigational trial. The trial will utilize four SCOUT DS devices. Subjects will report to the investigative site for multiple visits. The number of visits will vary between three to seven visits.
