Diabetes: Random blood sugar of 200 + is suggestive of diabetes if associated with symptoms of the latter - increased thirst, urination, appetite, weight loss, fatigue, etc. Strong sweet urine smell is often misinterpreted and heart palpitations is not a symptom of high blood sugar.
Dr. Gebrehana Zebro (formerly Woldegiorgis)

Yes: Diabetes show in random blood sugar . However , the standard test to diagnose diabetes is fasting blood sugar . I would recommend you have fasting blood sugar . If its is >124 , it fulfill the diagnostic criteria of diabetes according to ada.

Not always: Random glucose fluctuates. The more accurate blood test is the hemoglobin a1c which gives an average level over a period of weeks/months. Still it's good news that you had so many normal results.
