From Valparaiso, Indiana, USA:
Is there any evidence that A1c (glycohemoglobin) test results are affected by recent high daily readings (or a high same day reading) or by wide variation in daily readings?
HbA1c (glycohemoglobin) reflects average blood sugar over the previous 2-3 months. It is a relatively crude test that tells you nothing about blood sugars that make up the average (you can have the same average blood sugar with either wide or minimal variations in blood sugars) and it is not influenced neither does give you any information regarding short term (daily) blood sugar fluctuations.
