The glucose levels are extracted by a non-invasive technique that transmits low-power radio waves through a section of the human body, such as the area between the thumb and forefinger. These areas have an adequate blood supply and are thin enough for the waves to pass through the tissue. These signals are then received by a sensor on the opposite side of the etouchng device, where the data about the characteristics of the blood within the flesh are collected and analyzed.
The ETM-G01E Glucose Monitoring System is indicated for measuring interstitial fluid glucose levels in people (age 4 and older) with diabetes mellitus. The indication for children (age 4 – 12) is limited to those who are supervised by a caregiver who is at least 18 years of age.
