CGM systems available today measure glucose in the interstitial fluid – the fluid between your cells just under the skin. Since CGM is measuring glucose in a different part of your body, it will not be the same concentration as in your blood, but very similar. A blood glucose meter requires that you take a small sample of blood from your fingertip and place it on a test strip that’s inserted inside a meter. The meter provides a glucose value based on the amount of glucose in the blood sample at that moment.
CGM automatically and continuously provides glucose values every few minutes, using a sensor inserted just below your skin. The glucose level taken from your blood can be different from the glucose level in the fluid below your skin. With ordinary CGM and FGM systems, you must insert a new sensor through the skin every 7-14 days. With the Vita Medicorp LLC CGM System, a single sensor lasts for months.
