Blood glucose monitoring devices are devices that help you measure your blood sugar levels at home or on the go. They can help you manage your diabetes and prevent complications by alerting you to high or low blood sugar levels. There are different types of blood glucose monitoring devices, such as: Traditional blood glucose meters : These are devices that measure your blood sugar levels from a small drop of blood obtained by pricking your finger with a lancet. You place the blood drop on a test strip that is inserted into the meter, and the meter displays the result on a screen within seconds. You may need to calibrate the meter and the test strips with a control solution before using them. Continuous glucose monitors (CGMs) : These are devices that measure your blood sugar levels every few minutes from a small sensor inserted under your skin. The sensor sends the data wirelessly to a receiver or a compatible smartphone app, where you can see your current level, trends, and alerts. Y
