Free Glucometers (Blood Glucometers)
When people with diabetes can control their high blood sugar (glucose), they are more likely to stay healthy. People with diabetes use two kinds of management devices: glucometers and other diabetes management tests. Glucometers help people with diabetes check their blood sugar at home, school, work, and play. Other blood and urine tests reveal trends in diabetes management and help identify diabetes complications.

Glucometers
Self-Monitoring of Blood GlucoseThe process of monitoring one's own blood glucose with a glucometer is often referred to as self-monitoring of blood glucose or "SMBG."
To test for glucose with a typical glucometer, place a small sample of blood on a disposable "test strip" and place the strip in the meter. The test strips are coated with chemicals (glucose oxidase, dehydrogenase, or hexokinase) that combine with glucose in blood. The meter measures how much glucose is present. Meters do this in different ways. Some measure the amount of electricity that can pass through the sample. Others measure how much light reflects from it. The meter displays the glucose level as a number. Several new models can record and store a number of test results. Some models can connect to personal computers to store test results or print them out.
