Blood glucose monitoring

Definition:

Blood glucose monitoring is a measurement of glucose (sugar) in the blood. The test can be done at any time on a portable machine. It can be a self-test for a person with diabetes.

Alternative Names:

Glucose monitoring; Random glucose; Glucose - random; Serum glucose - random; self monitoring of blood glucose

How the test is performed:

The finger is pricked and a drop of blood is put on a special strip, which uses a chemical substance to determine 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.

How to prepare for the test:

Have all test items within reach before starting -- timing is important. Clean the area with soap and water or an alcohol swab. The area needs to be completely dry before pricking.

How the test will feel:

There is a sharp prick.

Why the test is performed:

The test allows the person with diabetes to carefully monitor blood glucose levels, to assure that they are within the normal range. The individual can then respond quickly to high or low blood sugar levels (hyperglycemia or hypoglycemia) with appropriate intervention. Such intervention includes adjusting diet, exercise, and insulin dose as instructed by your physician.

This test can also be a screening test for blood glucose levels.
