Good Evening I hope some nice person can clear something up for me, i was diagnosed Type2 in September 2010 and on diet only except for a daily statin, everyone i speak to about diagnosis tells me they had this 2 hour test after having a drink at the doctors and then waiting at the surgery until the time was up and getting there results,I have never had this test and it has never even been discussed,can anyone tell me how they arrive at my diagnosis without this test,i am not in denial just puzzled and concerned HELP.

Most type 2s nowadays are diagnosed on the basis of the HbA1c test, a simple blood test from which your average sugar levels over the previous 2 to 3 months can be found. that's how I was diagnosed. You can, however, also diagnose on the basis of how a person reacts over a period to a glucose drink which is what you're referring to. It's known as a glucose tolerance test.

A lot of people never have or need a glucose tolerance test. Until recently these were the criteria for a diagnosis of diabetes
1. Diabetes symptoms (ie polyuria, polydipsia and unexplained weight loss) plus
a random venous plasma glucose concentration > 11.1 mmol/l
or
a fasting plasma glucose concentration > 7.0 mmol/l (whole blood > 6.1mmol/l)
or
two hour plasma glucose concentration > 11.1 mmol/l two hours after 75g anhydrous glucose in an oral glucose tolerance test (OGTT).
2. With no symptoms diagnosis should not be based on a single glucose determination but requires confirmatory plasma venous determination. At least one additional glucose test result on another day with a value in the diabetic range is essential, either fasting, from a random sample or from the two hour post glucose load. If the fasting or random values are not diagnostic the two hour value should be used
So unless you have symptoms, then normally two fasting readings over 7mmol are sufficient for a diagnosis. A glucose tolerance test isn't necessary.
Recently it was decided that an HbA1c could be used for diagnosis(this blood test reflects your blood glucose levels over the last 3 months). An An HbA1c of 48 mmol/mol (6.5%) is recommended as the cut point for diagnosing diabetes
A value of less than 48 mmol/mol (6.5%) does not exclude diabetes diagnosed using glucose tests
