Final answer:
Patients with diabetes monitor their blood sugars using a portable machine called a glucometer, which measures the level of glucose in the blood. A drop of blood is placed on a test strip, and the meter reads the test strip to determine the glucose level.
Step-by-step explanation:
Patients with diabetes monitor their blood sugars by using a portable machine called a glucometer. A glucometer is used to measure the level of glucose in the blood.
It works by placing a drop of blood on a test strip, which is read by the meter. The test strip contains enzymes that react with glucose to produce a color change, and the intensity of the color change is directly proportional to the amount of glucose in the blood.
