Blood glucose monitoring

• Overview
• Risks
• Results

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.
