It depends on the type of diabetes test you are taking:
- A1C Test: No fasting is required. This test measures your average blood sugar levels over the past 2-3 months.
- Fasting Blood Glucose Test: Yes, you need to fast for at least 8 hours before this test. It measures your blood sugar levels after fasting.
- Oral Glucose Tolerance Test (OGTT): Fasting is required. You will fast overnight, and then your blood sugar is tested before and after drinking a glucose-rich drink.
Always follow your healthcare provider's instructions for accurate results.
