Glucose Meters: Glucose meters are handheld devices that measure blood sugar levels using a small drop of blood. To use a glucose meter, a lancet is used to prick the finger and a small drop of blood is placed on a test strip, which is inserted into the meter. The meter then provides a reading of the blood sugar level.
Continuous Glucose Monitoring (CGM): CGM systems use a small sensor that is inserted under the skin to continuously measure glucose levels in the fluid between cells. The sensor sends this information to a receiver, which displays the glucose levels in real-time. Some CGM systems can also provide alerts when glucose levels are too high or too low.
Laboratory Tests: Blood sugar levels can also be measured through laboratory tests, which involve drawing blood and analyzing it in a laboratory. These tests are usually performed by a healthcare professional.
It is important to monitor blood sugar levels regularly if you have diabetes or are at risk for diabetes. Your healthcare provider can help you determine the best method for monitoring your blood sugar levels and how often you should do so.
