|---|---|---|---|---|
| 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. |

| 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-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). | 1 hour |
