Diabetes
Conditions
Brief summary
The purpose of this study was to determine if untrained subjects who have diabetes can operate the Investigational Blood Glucose Monitoring System (BGMS) and obtain valid glucose results.
Interventions
Untrained subjects with diabetes self-tested capillary fingerstick and palm blood using the NINJA 3 Investigational Blood Glucose Monitoring System. Study staff tested subject fingerstick blood. All BG results were compared to reference method results obtained from subject capillary plasma.

Untrained subjects with diabetes 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 +/- 15mg/dL (\<75mg/dL YSI capillary plasma) or +/- 20% (\>=75mg/dL YSI capillary plasma).
Time frame: 1 hour
Population: 218 (219-1) Blood glucose results were analyzed. One subject discontinued from testing after low Blood Glucose (BG) fingerstick result (hypoglycemia AE), thus no reference result available for that subject.
