A patient with suspected diabetes has FBS 8.0 mmol/L, RBS 12.0 mmol/L, 2h OGTT 14.0 mmol/L. What is the diagnosis?

Glucose tests have clear thresholds used to diagnose diabetes. A fasting plasma glucose of 7.0 mmol/L or higher confirms diabetes, and this patient has 8.0 mmol/L. The oral glucose tolerance test looks at the 2-hour plasma glucose after a 75 g glucose load; a value of 11.1 mmol/L or higher confirms diabetes, and this patient has 14.0 mmol/L at 2 hours. The random glucose of 12.0 mmol/L is also elevated, but the key point is that the fasting and 2-hour values already meet the diabetes criteria. Prediabetes would show intermediate values (not this high), hyperglycemia is a general term rather than a diagnosis, and normal would not fit. Therefore, the diagnosis is diabetes mellitus.
