Arm Intervention/treatment
Experimental: Intended Users of the Monitoring System
Untrained subjects with diabetes use the G3 investigational blood glucose monitoring system.
 Device: G3 Investigational Blood Glucose Monitoring System
Untrained subjects with diabetes perform self Blood Glucose (BG) tests with capillary fingerstick blood and AST of the palm using the G3 meter and an investigational sensor. Study staff test subject venous blood and all BG results are compared to a reference laboratory glucose method. Untrained subjects utilize some additional features of the meter using the User Guide and provide feedback.


Outcome Measures

Primary Outcome Measures :
  1. Percent of Self-Test Fingerstick Blood Glucose Results Within +/- 5to15mg/dL (<100mg/dL) or Within +/- 5to15% (>=100mg/dL) of Laboratory Glucose Method [ Time Frame: 1 hour ]
    Untrained subjects with diabetes self-test fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS results are compared with capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer BG results are used to calculate the number of BGMS results within +/- 5to15mg/dL (<100mg/dL YSI capillary plasma) or +/- 5to15% (>=100mg/dL YSI capillary plasma). Site staff tested in parallel after subjects.


Secondary Outcome Measures :
  1. Percent of Glucose Results From Alternative Site Testing (AST) of the Palm Within +/- 15mg/dL (<75mg/dL) or Within +/- 20% (>=75mg/dL) of Laboratory Glucose Method [ Time Frame: 1 hour ]
    Untrained subjects with diabetes self-test Alternative Site (AST) Palm blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS AST results are compared with capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI capillary plasma BG results are used to calculate the number of AST BGMS results within +/- 15mg/dL (<75mg/dL YSI capillary plasma) or +/- 20% (>=75mg/dL YSI capillary plasma).

  2. Percent of Venous Blood Glucose Results Within +/- 5to15mg/dL (<75mg/dL) or Within +/- 5to20% (>=75mg/dL) of Laboratory Glucose Method [ Time Frame: 1 hour ]
    Study staff tested subject venous blood using an investigational Blood Glucose Monitoring System (BGMS). Venous BGMS results are compared with venous plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI venous plasma results are used to calculate the number of BGMS results within +/- 5to15mg/dL (<75mg/dL YSI venous plasma) or +/- 5to20% (>=75mg/dL YSI venous plasma).

  3. Number of Subjects Able to Perform Given Tasks Using Product Labeling for Instruction [ Time Frame: 1 hour ]
    After reading the instructions for use, and without assistance from the study staff, subjects use the BGMS to utilize some of the additional features of the system. Study staff documents Yes or No 'Did the subject complete the task successfully?'
