Evaluation of an Karajishi TS Investigational Blood Glucose Monitoring System

User Performance of the Karajishi Contour TS Blood Glucose Monitoring System

The purpose of this study was to determine if subjects who have diabetes can operate the Investigational Blood Glucose Monitoring System (BGMS) with no training and obtain valid glucose results.

Intervention / Treatment

Experimental: Intended Users of the Monitoring System; Subjects with diabetes used the Karajishi TS Investigational Blood Glucose Monitoring System with no training. The criteria for the intended use population: At least 60% of subjects will be younger than age 65; At least 10% of subjects will have type 1 diabetes

Device: Karajishi TS Investigational Blood Glucose Monitoring System; Subjects with diabetes performed self Blood Glucose (BG) tests with capillary fingerstick and palm blood using the Karajishi TS Investigational Blood Glucose Monitoring System with no training. All BG results were compared to reference method results obtained from subject capillary plasma. Also, study staff tested subject venous blood and BG results were compared to reference method results obtained from subject venous plasma.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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	Subjects with diabetes self-tested fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS) with no training. 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).	1 hour

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Venous Blood Glucose (BG) Results Within +/- 15 mg/dL (<100 mg/dL) and Within +/- 15% (>=100 mg/dL) of Laboratory Glucose Method	Study staff tested subject venous blood 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).	1 hour
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	Subjects with diabetes self-tested Alternative Site (AST) palm blood using an investigational Blood Glucose Monitoring System (BGMS) with no training. BGMS AST palm 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).	1 hour
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	Study staff obtained and tested subject 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 +/-15 mg/dL (<100 mg/dL YSI capillary plasma) and +/-15% (>=100 mg/dL YSI capillary plasma).	1 hour
Number of Subject Responses That Strongly Agree or Agree or Are Neutral With Questionnaire Statements	Staff obtained subject responses using short questionnaires to provide feedback on instructions for use and the basic operation of the BGMS. Subjects could respond Strongly Agree; Agree; Neutral; Disagree; or Strongly Disagree.	1 hour
