Treatment and study plan

Karajishi Contour Investigational BG Monitoring System

Device

Subjects with diabetes perform self Blood Glucose (BG) tests with capillary fingerstick and palm blood using the Karajishi Contour Investigational BG Monitoring System with no training. All BG results are compared to reference method results obtained from subject capillary plasma. Also, study staff test subject venous blood and BG results are compared to reference method results obtained from subject venous plasma.

Primary outcomes

  1. 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 Method

    Time frame: 1 hour

    Subjects with diabetes self-test fingerstick blood use an investigational Blood Glucose Monitoring System (BGMS) with no training. BGMS results are compared with subject 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 +/-15 mg/dL (<100 mg/dL YSI capillary plasma) and +/-15% (>=100 mg/dL YSI capillary plasma).

Secondary outcomes

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

    Time frame: 1 hour

    Study staff test subject venous blood using an investigational Blood Glucose Monitoring System (BGMS). Venous BGMS results are compared with subject venous plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer venous plasma BG results are 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).

  2. Number of Blood Glucose (BG) Results From Alternative Site Testing (AST) Palm Blood Within +/- 15 mg/dL (<100 mg/dL) and Within +/- 15% (>=100 mg/dL) of Laboratory Glucose Method

    Time frame: 1 hour

    Subjects with diabetes self-test Alternative Site (AST) palm blood using an investigational Blood Glucose Monitoring System (BGMS) with no training. BGMS AST palm results are compared with subject 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 +/-15 mg/dL (<100 mg/dL YSI capillary plasma) and +/-15% (>=100 mg/dL YSI capillary plasma).

  3. Number of Subject Fingerstick Blood Glucose (BG) Results Within +/- 15 mg/dL (<100 mg/dL) and Within +/- 15% (>=100 mg/dL) of Laboratory Glucose Method When Obtained and Tested by Study Staff

    Time frame: 1 hour

    Study staff obtain and test subject fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS results are compared with subject capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI capillary plasma results are 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).

  4. Number of Subject Responses That Strongly Agree or Agree or Are Neutral With Questionnaire Statements

    Time frame: 1 hour

    Staff will obtain subject responses using short questionnaires to provide feedback on instructions for use and the basic operation of the BGMS. Subjects may respond Strongly Agree; Agree; Neutral; Disagree; or Strongly Disagree.
