What's funny is I had a 2 hour blood glucose test which was 90 (pre) - 120 (1hour post) - 90 (2 hours post), all great numbers according to my doc. My A1C is 5.3, again great. Fasting Glucose of 83 and 90 most recently.

But then, i can eat something like what you mentioned and really rise up to areas of 168 ish and hour or two after and see a very slow fall back to just barely below 100. It can sometimes have me hanging up at 100-105 into the next morning. Very odd.

The glucose drink used in the GTT is pure sugar and we often react fine in that test. But it is only 75g of sugar. There are meals that actually can go way above what you get on a GTT. Also things like Dairy will have your blood sugar slowly rise and slowly fall. So you can be sitting at a high reading for a while.

I myself put a lot more stock into results obtained from a needle that takes a lot more blood though. The glucose meters are ok but they are really only good for tracking how levels change and dramatic differences over time. Their accuracy can be off by 10 - 20 depending upon the meter. So, you can make yourself a little crazy over a reading of 105 when you may really be 90. Or a 180 that may be closer to 160.
