| Ninja 2 Investigational Blood Glucose Meter | Device | Untrained subjects with diabetes performed Blood Glucose(BG) tests from the subject's capillary blood obtained from fingerstick, palm, and forearm using the Ninja 2 investigational meter. All BG results were compared to a reference laboratory glucose method. Subjects' success at performing basic tasks using only the User Guide were rated by study staff. |

| Numbers of Fingerstick Blood Glucose (BG) Results Within +/- 5 to 15mg/dL (<75 mg/dL) or Within +/- 5% to 20% (>=75 mg/dL) of Laboratory Glucose Method | Subjects with diabetes tested subject fingerstick blood using an investigational blood glucose meter (BGM). BGM results were compared to a reference lab glucose method - Yellow Springs Instrument (YSI) Analyzer. BG results were used to calculate the number of BG results within +/- 5 to 15 mg/dL (for reference BG results <75mg/dL) or +/- 5 to 20% (for reference BG results >=75mg/dL) of the reference method results. | 2 hours |

BGM results were compared to a reference lab glucose method - Yellow Springs Instrument (YSI) Analyzer. BG results were used to calculate the number of BG results within +/- 5 to 15 mg/dL (for reference BG results <75mg/dL) or +/- 5% to 20% (for reference BG results >=75mg/dL) of the reference method results. |

| Number of Subjects Rated as<=3 Performing Basic Meter Tasks (Labeling Comprehension) | Subjects reviewed the instructions for use (User Guide and Quick Reference Guide) to learn to use the system. Study staff then observed and rated the subjects(1 to 4) on their success at performing the tasks. Scale: 1.Success in performing tasks correctly without assistance. 2.Successful with additional review of User Guide. 3.Successful with additional review and study staff assist similar to review of a specific function during a Customer Service call. 4.Subject did not perform task correctly and study staff intervention was required. | 2 hours |
