In brief: Go see your doctor
Assuming you are not pregnant, there are 4 ways to tell if you have diabetes.
If you have classic symptoms such as increased hunger, increased thirst, increased urination, or blurred vision with random blood glucose =/>200, 2 hour 75 gram glucose tolerance test =/>200, fasting blood glucose =/>126 (x2) or hemoglobin A1c =/>6.5. Please go see your doctor to evaluate you.

In brief: Blood test
A fasting glucose is a good start a 2 hour glucose tolerance test is recommended if the fasting is normal but you have risk factors for diabetes like obesity or a family history.

Random blood glucose and hemoglobin A1C are additional tools to diagnose diabetes. See link below. http://care.diabetesjournals.org/content/35/Supplement_1/S11/T2.expansion.html

In brief: Excess thirst
Excessive thirst, frequent urination are usually early symptoms.
If in doubt please get checked.

In brief: HbA1c,NMR,↑AfterFood
Hba1c (reflects average blood sugar of last 1-3 months) best, optimal ?5.
0%; ?6.5% is clear dm. Even better is NMR particle test insulin-resistance score (can detect ?10 years prior to hba1c ?6.5%). At home method, check peak blood glucose, 20-90 min after high carb meal, highest should be ?140 mg/dl. But this must be done many times, is more complex ; less effective; more hit ; miss.
