The Diabetes Sentry utilizes advanced sensors that make contact with the skin and continuously monitor the status of an individuals’ body chemistry. If the sensors detect a change in the initial automatic preset levels established when the Diabetes Sentry was first worn by the individual a loud audible warning alarm will sound. When this occurs it is recommended that the individual perform a blood test to determine if in fact a persons blood sugar levels are trending dangerously low.

NO. The Diabetes Sentry is only monitoring for the symptoms which may accompany hypoglycemia, namely perspiration and/or a drop in skin temperature. Either of these symptoms or a combination of both will trigger the alarm. If an alarm sounds you must do a blood test to determine blood sugar levels. You can not be sure that the alarm is sounding due to hypoglycemia, as perspiration of any kind will cause an alarm to sound, and some people may perspire at night for other reasons.
