Treatment and study plan

Investigational Blood Glucose Monitoring System

Device

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.

Primary outcomes

  1. 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

    Time frame: 2 hours

    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. 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

    Time frame: 2 hours

    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.

Secondary outcomes

  1. Number of Subjects Rated as<=3 Performing Basic Meter Tasks (Labeling Comprehension)

    Time frame: 2 hours

    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.
