The non invasive blood glucose monitor is the holy grail of glucose monitoring technology. Ever since the ability to check the level of glucose in the blood was first developed the technology and tools have been steadily improving, especially since the advent of the at home glucose monitor.
Not long ago, the ability to check the level of glucose in human blood was limited to the medical laboratory, then the first bulky at home machines were invented and blood glucose monitoring entered a whole new era. From those slow and bulky machines of yesterday the modern at home blood glucose monitor has evolved into a sleek and compact unit that fits easily in a pants or shirt pocket, can store more than two hundred memory entries with ease, and can read the glucose levels in a tiny drop of blood in fifteen second or less.
Regardless of the advancements made in technology, one aspect of the monitors has remained unchanged since their inception, and that is the need for blood to be drawn into the monitor via test strip for the glucose level to be checked. This of course had cause untold amounts of discomfort to millions of people because each glucose checks must be accompanied my poking a hole in the skin with a needle.
The newest trend in the quest for a better glucose monitor is the non invasive blood glucose monitor. These new inventions are worn like a wrist watch and sample the blood glucose level in interstitial fluid which is painlessly drawn through the sweat glands via a small electric charge. These non invasive blood glucose monitors are designed to be worn for up to twelve hours at a time with a sample taken as often as every twenty minutes. Many of these blood glucose monitors are equipped with an alarm that alerts the wearer if their blood glucose getting either too high or too low.
While the technology is not yet advanced enough for the non invasive blood glucose monitor to replace the standard variety, new advancements are being made every day, and one day soon everyone may be able to monitor their glucose without paying for it in blood.
