When someone mentions diabetic testing machines the device they are referring to is usually called a glucometer. Diabetic testing machines are designed to read the level of glucose, or sugar, in a drop of blood so that the blood sugar level can be tracked.

The use of diabetic testing machines is pretty simple and straight forward. To use the machine a special test strip is placed in the machine, then a drop of blood is collected by pricking the skin (usually on the finger) with a lancet, the drop of blood is placed on the test strip and the machine “reads” the amount of sugar (glucose) in the blood. Though there is a huge variety of different makes and models of diabetic testing machines on the market, they all work in virtually the same way, some may require a little smaller drop of blood and some may “read” the sugar level quicker than the others, but the basic principal remains the same.
