Diabetic blood test. Finger of a diabetic with a "glucometer" machine, used to measure the level of glucose in the blood. Diabetes mellitus is a carbohydrate metabolism disorder that results in dangerously high levels of glucose in the blood. Regular monitoring of blood glucose is therefore necessary. The patient's finger is pricked to extract a drop of blood. The blood is placed on a chemically-coated strip (silver, lower left) and inserted into the glucometer, which gives a glucose reading. Diabetes mellitus is normally caused by insufficient insulin production by the pancreas. Treatment includes controlling dietary sugar intake, and insulin injections.
