Whether you need to fast for a blood sugar test depends on the type of test being performed:

  • Fasting Blood Glucose Test: This test requires fasting for at least 8 hours before the test. It measures your blood sugar levels after a period of not eating.
  • A1C Test: This test does not require fasting. It measures your average blood sugar levels over the past 2-3 months.
  • Random Blood Sugar Test: This test can be done at any time, regardless of when you last ate.

Always follow your healthcare provider's instructions for preparing for a blood sugar test.
