Your readings were :
fast level - 5.5 (99 mg/dl)
1 hour - 15.6 (280 mg/dl)
2 hours - 12 (216 mg/dl)
Here are the diagnostic criteria from
http://www.endocrineweb.com/diabetes/diagnosis.html :
Quote:
Glucose tolerance tests may lead to one of the following diagnoses:
Normal Response
A person is said to have a normal response when the 2-hour glucose level is less than or equal to 110 mg/dl.
Impaired Fasting Glucose
When a person has a fasting glucose equal to or greater than 110 and less than 126 mg/dl, they are said to have impaired fasting glucose. This is considered a risk factor for future diabetes, and will likely trigger another test in the future, but by itself, does not make the diagnosis of diabetes.
Impaired Glucose Tolerance
A person is said to have impaired glucose tolerance when the 2-hour glucose results from the oral glucose tolerance test are greater than or equal to 140 but less than 200 mg/dl. This is also considered a risk factor for future diabetes. There has recently been discussion about lowering the upper value to 180 mg/dl to diagnose more mild diabetes to allow earlier intervention and hopefully prevention of diabetic complications.
Diabetes
A person has diabetes when oral glucose tolerance tests show that the blood glucose level at 2 hours is equal to or more than 200 mg/dl. This must be confirmed by a second test (any of the three) on another day. There has recently been discussion about lowering the upper value to 180 mg/dl to diagnose more people with mild diabetes to allow earlier intervention and hopefully prevention of diabetic complications.

It looks like you have diabetes to me. Your fasting level is fine. But your 1 hour and 2 hour GTT readings are way to high. The fact that your fasting levels are OK just means that that your diabetes is still at an early stage of development.
Cheers,
Mark
