  Fast for at least 8 hours. Here’s why…. While you have this HBA1C test done ,you will also get results for your fasting glucose level. That way you kill 2 birds with one stone. Also here is the new way that you can see what your average glucose level was. It give more acurate results than the old way…
  To convert an A1c to the new average mean blood glucose, use this formula:
  eAG(mg/dl) = (28.7 X HbA1c) – 46.7
  So the old method has an A1c of 6% at an average blood glucose of 135mg/Dl, and using the new formula will give you 126mg/DL, and a 7% A1c now equals a eAG of 154mg/DL instead of 170mg/DL.

  Hi,
  You do not need to fast for this test, unless you physician is going to do other test, in which, he/she has requested you to fast like for glucose or lipids. The Hgb A1C is measured to help your physician determine an estimated average glucose over the past 2-3 months. This helps he/she to determine if your adequately controlling your glucose levels.
  Hope this helps.

  You don’t have to fast for an A1C, however, make sure that is the only test your doctor is going to request.
