Do recent highs impact A1C draws?

I’m looking for some opinions here.

If you have something more concrete than an opinion, that’s even better.

I have a story to share, but I don’t have time to post about it right now. But due to the events in that story, I had the first reading of “Hi” on my meter last night (that means over 500 I think, or is it 600?) Either way, I was super high. I’ll tell you all about it another time. I was able to catch it middle of the night, and correct, and woke up this morning at 167 mg/dl. Feeling a little tired, but overall, not too bad.

Then I went and had breakfast – and totally forgot to bolus for it. Doh!! So, I caught that one a couple hours later, feeling yucky, with a test result of 350 mg/dl. What the hell was I thinking about that I forgot to bolus?! That’s the first time in many, many months that I’ve forgotten. If it were more common for me, I would utilize the “Missed Meal Bolus Alerts” that can be configured on my Cozmo. I don’t use them, because it just doesn’t happen very often.

I have my endo appointment a week from tomorrow, and I need to get my labs drawn so he has the results in time for the appointment. I have tomorrow and Monday off from work, and had planned on getting the labs drawn and out of the way tomorrow.

But – will my recent episodes of really high readings somehow skew the results for the A1C test? Would it “buy” me anything by going on Monday rather than tomorrow?

What are your thoughts on this? Cast your vote! Thanks!

I am glad recent highs don’t effect a1c, seeing as I am on prednisone now- the week before my a1c.


I have been reading these comments with interest, as I had no expert medical knowledge to toss in the ring myself. I have learned a lot, though. 🙂


My understanding of the A1C’s is the same as the other folks. It is an average for the last three months. So the recent highs should not affect the numbers as much.
Also it is an attenpt at getting the averages. So some spikes or lows do not make that much of a difference.
Good luck on your appointment.
