Usually need to fast 9-12 hours before a glucose test. Your result should be accurate. https://medlineplus.gov/lab-tests/fasting-for-a-blood-test/ If your test result is abnormal, you can repeat it under ideal conditions prior to initiating therapy for diabetes or prediabetes. HgbA1C tests your average blood sugar over the past 3 months. Avoid sugar while sick. It impairs the immune system.

An eight hour fast is sufficient for fasting blood glucose. A minimum of 9 hour fast is needed for blood lipid tests.

Agree with Dr Peltan, as doctors like to be certain that certain blood testing, such as glucose and cholesterol be conducted under fasting conditions. You probably will be OK at 11 hrs, but if levels of glucose are elevated, this could be repeated with longer fasting. Not a challenging problem in most cases.
