Glucose strips are small, disposable test strips used to measure the level of glucose in a person's blood. They are commonly used by individuals with diabetes to monitor their blood sugar levels. The strips work in conjunction with a glucometer, a device that reads the glucose level from a small blood sample applied to the strip. To use glucose strips, a person pricks their finger with a small needle, known as a lancing device, to obtain a drop of blood. The blood is then placed on the strip, and the glucometer provides a reading within seconds, helping users manage their condition effectively.
