The man pictured here, was about to check his blood glucose level. This process is known as self-monitoring blood glucose, and it is a way for people with diabetes to find out how much glucose is in their blood. A drop of blood from the fingertip is placed on a special coated strip of paper, revealing the amount of glucose in the blood. Many people use an electronic meter to get this reading. At this point, he was about to perform a controlled finger stick, using a mechanized needle, which would very quickly, and relatively painlessly, penetrate the skin, thereby, inducing the delivery of a blood droplet, which could then be tested.
