No: The simple answer is no. Checking glucose in the blood however is better done when fasting for 8 hrs. A random glucose level can be done as well but has to be interpreted with caution. Good luck.

Wondering what can cause rise in blood glucose while intermittent fasting, I had recent lab work that included A1C of 5.5. I have heard the fasting can cause a glucose rise from falling insulin levels and increase urine output (water loss). Accurate?
