Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Persons With Diabetes<br>Untrained Subjects WITH Diabetes Use the ONYX NEXT BGMS (Blood Glucose Monitoring System). | Device: ONYX NEXT BGMS<br>* Untrained Persons WITH Diabetes Use the ONYX NEXT BGMS (Blood Glucose Monitoring System). Subjects tested capillary fingerstick and palm blood (and study staff tested subject fingerstick blood) using the ONYX NEXT BGMS. All BG results were compared to reference method results obtained with subject capillary plasma. Also, study staff tested venous blood from subjects WITH Diabetes and BG results were compared to reference method results obtained from the subjects' venous plasma.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
