How Is Type 2 Diabetes Diagnosed? Essential Tests Explained
​Understanding your blood sugar numbers is the first step toward managing or preventing diabetes. In this guide, we break down the primary tests used to detect Type 2 Diabetes and what your results actually mean:
​Urine Tests: Detects glucose (Benedict’s Test) and ketone bodies (Rothera’s Test) to identify early metabolic changes.
​Fasting Blood Glucose Test (8–12 hours fasting): Normal is under 100 mg/dL, 100–125 mg/dL indicates prediabetes, and 126 mg/dL or above suggests diabetes.
​Postprandial Glucose Test (2 hours post-meal): Normal is under 140 mg/dL, 140–199 mg/dL indicates prediabetes, and 200 mg/dL or higher suggests diabetes.
​HbA1c Test (3-Month Blood Sugar Average): Under 5.7% is normal, 5.7% to 6.4% reflects prediabetes, and above 6.4% indicates diabetes (note: conditions like hemoglobinopathies can influence readings).
