How does a Blood Glucose Monitor Work?
About the size of a cell phone, a blood glucose monitor is a device that takes a drop of blood that has been applied to a test strip and provides an estimate of the blood glucose (sugar) concentration at that moment.
Blood glucose monitors can be used by following a few simple steps:
- A test strip is placed into the monitor – users should ensure that the test strip matches the monitor.
- A control solution is applied to the strip. This verifies that the strips are in good working condition.
- A lancet (small needle) is placed inside an adjustable lancing device and applied to the skin and depressed to draw a drop of blood.
- The drop of blood is placed on the test strip in the monitor to get a reading.
