Participant Group / Arm

Intervention / Treatment

Experimental: Intended Users of the Monitoring System; Untrained subjects with diabetes use an investigational blood glucose monitoring system.

Device: Investigational Blood Glucose Monitoring System; Untrained subjects with diabetes performed Blood Glucose (BG) tests with subject's capillary fingerstick using the investigational Tradewind meter and investigational sensor. Study staff tested subject venous blood. All BG Results were compared to a reference laboratory glucose method. Subjects' success at performing basic tasks using only the User Guide were rated by study staff.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percent of Capillary Blood Glucose (BG) Results Within +/- 5 to 20mg/dL (<75 mg/dL) or Within +/- 5% to 20% (>=75 mg/dL) of Laboratory Glucose Method	Subjects with diabetes used an investigational blood glucose monitoring system (BGMS) with subject capillary blood. BGM results were compared to a reference lab glucose method - Yellow Springs Instrument (YSI) Analyzer. BG results were used to calculate the number of BG results within +/- 5 to 20 mg/dL (for reference BG results <75mg/dL) or +/- 5 to 20% (for reference BG results >=75mg/dL) of the reference method results.	2 hours
Percent of Venous Blood Glucose (BG) Results Within +/- 5 to 20 mg/dL (<75 mg/dL) or Within +/- 5% to 20% (>=75 mg/dL) of Laboratory Glucose Method	Healthcare professionals (study staff) used an investigational blood glucose monitoring system (BGMS) with subject venous blood. BGM results were compared to a reference lab glucose method - Yellow Springs Instrument (YSI) Analyzer. BG results were used to calculate the number of BG results within +/- 5 to 20 mg/dL (for reference BG results <75mg/dL) or +/- 5% to 20% (for reference BG results >=75mg/dL) of the reference method results.	2 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Subjects Rated as<=3 Performing Basic Meter Tasks (Labeling Comprehension)	Subjects reviewed the instructions for use (User Guide and Quick Reference Guide) to learn to use the system. Study staff then observed and rated the subjects (1 to 4) on their success at performing five tasks. Scale: 1.Success in performing tasks correctly without assistance. 2.Successful with additional review of User Guide. 3.Successful with additional review and study staff assist similar to review of a specific function during a Customer Service call. 4.Subject did not perform task correctly and study staff intervention was required.	2 hours
