Diabetes: How Do Glucose Meters Work?
When blood is placed onto a blood glucose meter test strip, it reacts with glucose oxidase producing gluconic acid from the glucose in the blood. At the other end of the test strip, the meter transfers a current to the test strip. The test strip has electric terminals which allow the meter to measure the current between the terminals. The current between the terminals changes depending on the level of gluconic acid that has been produced. The blood glucose meter then uses an algorithm to work out the blood glucose level based upon the difference in current. A glucose meter 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 home blood glucose monitoring (HBGM) by people with diabetes mellitus or hypoglycemia. A small drop of blood, obtained by pricking the skin with a lancet, is placed on a disposable test strip that the meter reads and uses to calculate the blood glucose level. The meter then displays the level in units of mg/dl or mmol/l. There are many companies who provide glucose meters and also selling Diabetic Test S Continue reading >>
