Controlling blood glucose levels
normal blood sugar level
The simplest way to detect diabetes is to look for glucose in the urine. A glucose test stick changes colour to indicate the level of glucose.
Diabetics regularly monitor their blood glucose level by using a digital monitor. A drop of blood is placed on a test strip and the monitor displays the blood glucose concentration.
Glucose tolerance test
To confirm diabetes, a person will normally take a glucose tolerance test in a hospital.
Patients do not eat for 12 hours before the test. This gets their blood glucose to its lowest level. They are then given a drink containing 75g of glucose and their blood glucose level is monitored over the next two hours.
Diabetics will rapidly become hyperglycaemic. Their blood glucose level rises and remains above normal.
