Noninvasive glucose monitoring ( NIGM ), called Noninvasive continuous glucose monitoring when used as a CGM technique, is the measurement of blood glucose levels, required by people with diabetes to prevent both chronic and acute complications from the disease, without drawing blood, puncturing the skin, or causing pain or trauma.
As a consequence, in conjunction with insulin administrations, the prime requirement for diabetic patients is to regularly monitor their blood glucose levels. [2] The monitoring systems currently in general use have the drawback of below optimal number of readings, due to their reliance on a drop of fresh blood. Some continuous glucose monitors ...
Four generations of blood glucose meter, c. 1991–2005. Sample sizes vary from 30 to 0.3 μl. Test times vary from 5 seconds to 2 minutes (modern meters typically require less than 15 seconds). A blood glucose meter is an electronic device for measuring the blood glucose level. A relatively small drop of blood is placed on a disposable test ...
A continuous glucose monitor ( CGM) is a device used for monitoring blood glucose on a continual basis instead of monitoring glucose levels periodically by drawing a drop of blood from a finger. This is known as continuous glucose monitoring. CGMs are used by people who treat their diabetes with insulin, for example people with type 1 diabetes ...
A glucose meter, also referred to as a " glucometer ", [ 1] is a medical device for determining the approximate concentration of glucose in the blood. It can also be a strip of glucose paper dipped into a substance and measured to the glucose chart. It is a key element of glucose testing, including home blood glucose monitoring (HBGM) performed ...
The technology that goes into the ICGM system consists of two parts. Primarily is the internal sensor which utilizes chemical reactions to determine blood glucose levels. Additionally, is an external receiver used to display glucose readings and patterns in real-time, hoping to help reduce the level of care needed in diabetics.
According to the American Diabetes Association, the fasting blood glucose target range for diabetics, should be 3.9 - 7.2 mmol/L (70 - 130 mg/dL) and less than 10 mmol/L (180 mg/dL) two hours after meals (as measured by a blood glucose monitor). [ 6][ 7][ 9] Normal value ranges may vary slightly between laboratories.
In 2004 continuous glucose monitoring (CGM) was introduced. A small sensor placed under the skin for three days (by 2013 up to 14 days) would measure glucose continuously and transmit the results to a receiver, which would periodically be connected to a PC to produce reports for the health care provider.
