Primary Outcome Measures
NameTimeMethod
Number of Self-Test Fingerstick Blood Glucose (BG) Results Within +/- 15 mg/dL (<100 mg/dL) and Within +/- 15% (>=100 mg/dL) of Laboratory Glucose Method1 hour

Untrained subjects WITH diabetes (329) self-tested fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS results were compared with subject capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer BG results were used to calculate the number of BGMS results within +/-15 mg/dL (\<100 mg/dL YSI capillary plasma) and +/-15% (\>=100 mg/dL YSI capillary plasma).

Secondary Outcome Measures
NameTimeMethod
Number of Self-Test Fingerstick Blood Glucose (BG) Results Within +/- 20% of Laboratory Glucose Method Across the Tested Glucose Range1 hour

Untrained subjects WITH diabetes (329) and WITHOUT diabetes (43) self-tested fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS results were compared with subject capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer BG results were used to calculate the number of BGMS results within +/-20% of the laboratory method across the entire tested YSI glucose range.

Number of Venous Blood Glucose (BG) Results Within +/- 15 mg/dL (<100 mg/dL) and Within +/- 15% (>=100 mg/dL) of Laboratory Glucose Method1 hour

Study staff tested venous blood of subjects WITH diabetes (329) using an investigational Blood Glucose Monitoring System (BGMS). Venous BGMS results were compared with subject venous plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer venous plasma BG results were used to calculate the number of BGMS results within +/-15 mg/dL (\<100 mg/dL YSI venous plasma) and +/-15% (\>=100 mg/dL YSI venous plasma).

Number of Responses From Persons With Diabetes That Either 'Strongly Agree' or 'Agree' or Are 'Neutral' With Questionnaire Statements1 hour

Staff obtained responses from persons WITH diabetes (329) using short questionnaires to provide feedback on instructions for use and the basic operation of the BGMS. Subjects could respond 'Strongly Agree' or 'Agree' or 'Neutral' or 'Disagree' or 'Strongly Disagree.'

Number of Subject Responses That Either 'Strongly Agree' or 'Agree' or Are 'Neutral' With Questionnaire Statements1 hour

Staff obtained responses from subjects WITH and WITHOUT diabetes using short questionnaires to provide feedback on instructions for use and the basic operation of the BGMS. Subjects could respond 'Strongly Agree' or 'Agree' or 'Neutral' or 'Disagree' or 'Strongly Disagree.'

Number of Subject Fingerstick Blood Glucose (BG) Results Within +/- 20% of Laboratory Glucose Method When Obtained and Tested by Study Staff1 hour

Study staff obtained and tested subject (WITH and WITHOUT diabetes) fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS results were compared with subject capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI capillary plasma results were used to calculate the number of BGMS results within +/-20% across the tested YSI glucose range.
