Outcome Measures
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
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).
1 hour
Secondary Outcomes (8)
Number of Venous Blood Glucose (BG) Results Within +/- 15 mg/dL (<100 mg/dL) and Within +/- 15% (>=100 mg/dL) of Laboratory Glucose Method
1 hour
Number of 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
1 hour
Number of Responses From Persons With Diabetes That Either 'Strongly Agree' or 'Agree' or Are 'Neutral' With Questionnaire Statements
1 hour
Number of Self-Test Fingerstick Blood Glucose (BG) Results Within +/- 15% of Laboratory Glucose Method Across the Tested Glucose Range
1 hour
Number of Self-Test Fingerstick Blood Glucose (BG) Results Within +/- 20% of Laboratory Glucose Method Across the Tested Glucose Range

Study Arms (2)
Persons With Diabetes
EXPERIMENTALUntrained subjects WITH Diabetes use Karajishi Contour BGMS (Blood Glucose Monitoring System).
Persons With and Without Diabetes
EXPERIMENTALUntrained subjects WITH/WITHOUT Diabetes use Karajishi Contour BGMS (Blood Glucose Monitoring System).
Interventions
Untrained subjects WITH and WITHOUT diabetes use Karajishi Contour BGMS (Blood Glucose Monitoring System). Subjects tested capillary fingerstick blood (and study staff tested subject fingerstick blood) using the Karajishi Contour BGMS. All BG results were compared to reference method results obtained with subject capillary plasma. Also, study staff tested subject venous blood and BG results were compared to reference method results obtained from subject venous plasma.

Eligibility Criteria
You may qualify if:
- Males and females, 18 years of age and older
- Able to speak, read, and understand English
- Willing to complete all study procedures
You may not qualify if:
- Hemophilia or any other bleeding disorder
- Pregnancy
- Physical, visual, or neurological impairments that would make the person unable to perform testing with the BGM
- Previously participated in a BG monitor study using the Karajishi Contour BGMS (or used a Bayer Contour meter)
- Work for a medical laboratory, hospital, or other clinical setting that involves training on and clinical use of blood glucose monitors
- Work for a competitive medical device company, or having an immediate family member who works for such a company
- A condition which, in the opinion of the investigator or designee, would put the person or study conduct at risk
- General enrollment guidelines:
- Most subjects will be persons with type 1 or type 2 diabetes
- At least 10% of subjects with diabetes will have type 1 diabetes
- Approximately 10% of subjects will be persons without diabetes
- At least 60% of subjects will be younger than age 65
