The tests are fasting blood glucose test, HBA1C, and post prandial blood test.
You dont have to fast for 14 hours until and unless prescribed a by a doctor.
Mornings are the best time to take the test.
Food nutrients can interfere with the test especially in the case of fasting blood glucose hence it is advised to remain empty stomach before giving the test.
For fasting blood glucose test one should not eat anything before the blood test.
