Diabetes
Conditions
Brief summary
The purpose of this study was to determine if untrained subjects with diabetes could perform basic tasks with the Styx lancing device to obtain adequate blood volume from fingerstick and palm lancings for Blood Glucose Meter testing.
Interventions
Untrained Persons With Diabetes used the Styx Lancing Device with 28 and 30 Gauge lancets to obtain fingerstick and Alternate Site palm capillary blood. Study Staff tested the capillary blood using Contour NEXT Blood Glucose Meters (BGMs) and recorded the results. Meter results could be numeric, non-numeric (ie, error messages), or not obtained at all.
