Blood glucose monitoring is a measurement of glucose in the blood that can be done at any time on a portable machine. It can be a self-test for the diabetic.How the test is performed Return to top
The finger is pricked and a drop of blood is put on a reagent strip, which uses a chemical substance to react to the amount of glucose in the blood. The meter then reads the strip and displays the results as a number on a digital display. Newer monitors can use blood from other areas of the body besides the fingers, reducing discomfort.
