| The answer is an unequivicable no. The A1c doesn't just tell you how much glucose is attached to the hemaglobin at the time of the test, it tells you how much has been attached on average. Remember, blood cells live a finite period of time. New blood cells would inevitibly be carrying less amounts of glucose than older blood cells, hence the "average" term used for the results of the test.
Because of this offset between newer and older blood cells, a "current" reading of extremely high BGL would not immediately effect an A1c, because it takes time for glucose to attach to a blood cell. Having said that, certainly having a high BGL like that over a period of time would raise your A1c results.
My first A1c was 13.6. My BGL at the time of initial contact with my doctor (prediagnosis) was 452. Based on figures I've been able to work out, my average BGL had been around 430 before I was diagnosed.
I hope that answers your question, if not, please let me know, and I'll try to explain it in more detail.
Regards,
Darian
