Diabetes affects over 2 million people in the UK and tends to effect adults over 40 and overweight people. Diabetes is a "silent" illness and first occurs without symptoms and left undetected and untreated can lead to kidney failure, impaired eyesight, nerve damage and cardiovascular risk. Increased glucose levels in urine indicate diabetes is already at a late stage therefore early detection of high glucose levels in the blood is crucial. This simple blood test gives an early indication of whether your blood glucose level is within normal limits.
