Summary: A glucose monitor, or glucometer, works by having an electrochemical cell read the current created by a reaction between blood and a glucose oxidase enzyme. Learn about how glucometers have evolved over the years with help from a licensed RN in this free video on glucose monitors.

"Hi, my name's Kayti Brosnan. I'm a registered nurse here in Austin, Texas and today, the question is how does a glucose monitor meter work. This can also be called a glucometer. So basically, this is something that has evolved over many years and currently, we're using products that have a glucose oxidase enzyme present in the test strip and so this being present in the test strip is what the blood that you're sampling first connects with and this is going to create a current. The current is going to be picked up within the monitor. There is a device in there that has an electrochemical cell. This picks up the current and it produces the results of what the blood glucose level is, so it's those two components, the glucose oxidase enzyme and then the electrochemical cell within the device that is producing the result, and that's the basic components of how a blood glucose monitor meter works."
