Blood glucose monitoring refers to the ongoing measurement of blood sugar (glucose). Monitoring can be done at any time using a portable device called a glucometer.

How the Test is Performed
The traditional glucose meter comes with test strips, small needles called lancets, and a logbook for recording your numbers. There are many different kinds of these meters, but they all work essentially the same way.
A complete testing kit can be purchased from a pharmacy without a prescription. Your doctor or nurse can help you choose the equipment that's right for you, help you set it up, and teach you how to use it.
You will prick your finger with the lancet and place a drop of blood on a special strip. This strip uses a chemical substance to determine the amount of glucose in the blood. (Newer monitors can use blood from other areas of the body besides the fingers, reducing discomfort.) The meter displays your blood sugar results as a number on a digital display.
How to Prepare for the Test
Have all test items within reach before starting -- timing is important. Clean the needle prick area with soap and water or an alcohol swab. Completely dry the skin before pricking.
