SMSI® Glucose Sensor
Personal Glucose Monitoring

Worldwide spending on glucose monitoring products is estimated at over $8.5 billion per year and is growing. Yet, despite increasing evidence that more frequent monitoring would enable improved control, among insulin-using patients in particular, many patients do not check their glucose levels at the frequency suggested. On average, insulin-using patients check their blood sugar less than twice daily.

Principal reasons for non-compliance with prescribed monitoring approaches are the pain and inconvenience involved in lancing a finger or arm to obtain a blood sample for glucose measurement. The finger has a particularly high density of capillaries, making it an ideal site for a blood sample, but it also has a high density of nerve-endings, making it a particularly painful site for puncture.

Standard glucose monitoring can be clinically complex and cumbersome, often leading to discouraging compliance. Existing glucose monitors experience error (including user error) up to 15-20% or more compared with the best standard bench-top analyzers. According to the American Diabetes Association, physicians believe that an error of 10% or less is needed to achieve clinically relevant endpoints in blood glucose control. To SMSI®'s knowledge, no home blood glucose monitors have been able to demonstrate a total error within this range.

Regardless of the reasons for non-compliance in testing, or the accuracy limitations of the readings, there is a widespread desire for an accurate, automatic, pain-free, continuous glucose monitor.
