You can monitor your blood glucose level using a digital meter. The method of use varies, depending on the type of meter, so you should follow the manufacturer’s instructions. However, using most meters involves applying a drop of blood to a test strip impregnated with a chemical that reacts with glucose. Checking your blood glucose at least once a day, or as often as recommended by your doctor or nurse, allows you to monitor your treatment to confirm that it is effective and to alter it as necessary.
Before starting, test or calibrate your meter, if necessary. Wash and dry your hands, then obtain a drop of blood by using a spring-loaded lancing device against the side of your finger.
Apply the blood to the pad on the end of the testing strip. The meter analyses the blood and gives a rapid reading (typically within 5–45 seconds) of the blood glucose level.
