Capillary And Venous Accuracy: LifeScan Products vs Hospital Reference and YSI

This study will gather data to: * Determine if extreme bias can be observed between 3 candidate products for user accuracy. * Assess the offset between venous blood samples versus capillary blood samples. * Determine if there are measurable donor factors which influence the product bias. * Assess any offset between YSI 2300 reference instruments and hospital laboratory analyser and impact on bias difference between BGM product types.
