Blood Glucose Meter

When diabetics measure their blood sugar levels with the use of a blood glucose meter it is known as SMBG, self-monitoring of blood glucose. These small medical devices are battery operated and easy to use.

Using a Blood Glucose Meter

In order to use a blood glucose meter individuals will need to prick their finger, place a drop of blood on a disposable testing strip, and then insert the strip in the blood glucose meter. There are various chemicals on the testing strips that will react with the blood glucose. These chemicals include oxidase, hexokinase, and dehydrogenase. The meter "reads" the blood sample by either measuring how much electricity can go through the blood sample or how much light is reflected by the sample. This occurs within three to 60 seconds and the reading will be displayed as a number. This number represents the individual's blood glucose level.

Blood Glucose Meter Results

Newer blood glucose meter models are able to store a certain amount of test results to improve management of blood sugar levels. Some diabetics prefer the blood glucose meters that may be connected to their computer and the test results printed or saved.

Choosing a Blood Glucose Meter

There are many blood glucose meters on the market. In order to determine the right one, patients should evaluate their needs first. The differences in blood glucose meters include size, memory, testing speed, meter cost, cost of necessary test strips, and amount of blood needed for testing. Some meters have larger displays for the visually impaired or automatic calibration to ensure more accurate readings.

Alternative Testing Sites for Blood Glucose Meter

Some older blood glucose meters required a full drop of blood to measure blood glucose levels. However, newer many newer models do not require as much blood allowing for alternative testing sites, including the forearms and thighs,

When to Use a Blood Glucose Meter

Diabetics will work with their doctor to create a personalized care plan. Some patients may need to use a blood glucose meter various times per day while others won't need to check their blood sugar as often. Diabetics who use insulin will need to check their blood sugar levels frequently with the help of a blood glucose meter while those with type 2 diabetes who manage the disease through diet alone may not need to use a blood glucose meter. Diabetics should work closely with their health care provider to ensure they receive the best care for their diabetes as is possible.
