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?

If you are talking about the testing strips. The part of the strip where you place the blood contains an enzyme that reacts with the sugar in your blood. When it is inserted into the machine, the machine measures the concentration of the product of the enzyme reacting with the sugar and then uses that to calculate the concentration of sugar in your blood.
