Diabetes is diagnosed quite simply by measuring the levels of glucose in the blood. The normal levels are between 3,3 mmol/l and 5,9 mmol/l.
The World Health Organisation defines diabetes

as being when one or more of the following are present:
Fasting blood glucose (blood glucose measured before breakfast) is over 6.7 mmol/l on two separate occasions
Random blood glucose (blood glucose measured at any time) is over 10 mmol/l
Keywords
diabetes, diagnosis of type 2 diabetes, diabetes, glucose, insulin
2 hour blood glucose during glucose tolerance test is over 10 mmol/l
Corresponding values for plasma glucose are 7.8 mml/l and 11.1 mmol/l
In some laboratories the glucose level is measured in plasma and not in blood and the concentration of glucose measured in plasma is 10% greater than that in whole blood
What is a glucose tolerance test?
After an overnight fast, 75 mg of glucose is taken in 250-300 ml of water
Blood samples are taken in the fasting state and two hours after the glucose has been taken
It is used to diagnose glucose intolerance
When is glucose tolerance impaired?
It is present when the fasting blood glucose is below 6.7 mmol/l and the 2 hour blood glucose value is between 6.7 and 10 mmol/l
Corresponding values for plasma glucose are 7.8 mml/l and 11.1 mmol/l.
