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.

Recently, I had a diagnostic test done for insurance purposes. I was diagnosed with a fasting blood sugar of 164 and an HbA1c level of 9, and my insurance was rejected stating that I am diabetic. I would like to know more since no doctor opinion was taken?
