I’m talking about those machines we use at home to measure the amount of glucose in our blood. How does that little machine measure glucose? Does it count the glucose? How?

Most glucometers today use an chemistry to create a tiny electric current that the meter can measure.

The test strips contain a capillary, a tiny tube that sucks in a specific amount of blood. The glucose in the blood reacts with chemicals in the test strip which generates an electric current. Since the amount of overall blood is always the same, only the amount of glucose in that blood varies and so does the current that is generated.
