Default 20 Minutes after eating too soon?

I just had 12 piece chicken nugget meal at mcdonalds with soda and tested 15-20 mins after I ate and results were 152, I washed hands and it was 142...ten tried other measures afterwards and all had same range.

Then 20 later it's down to the range of 100-115.

So my question is:

Do they recommend to test 1-2 hours after eating because anything before 1 hour will show high or low score?

Thanks

I wanted to test because I've been feeling really tired lately, but then again I stopped working out and feel into a depression.

Whatever we swallow will appear as blood glucose at varying times. Fast acting stuff like glucose (the soda?) will start to appear after 15 to 20 minutes as it does not need digestion. Other items take longer to show.

The one hour test will typically show the peak figure for a normal meal and at two hours, the digestion process should be more or less complete and your numbers should be starting to tail down.

Very slow carbs (pasta and general grain products) can take two and three hours to go through so when the meal is heavy in that area, a test at three hours is sensible.

As John said, times can vary. No we don't wait because we know it will be higher, we want to catch the high and avoid going over 140 (7.8) ever. Testing every 5 minutes to catch that is quite impractical due to costs of test strips for most of us. We also tend to avoid the need by avoiding carbs, especially the fast acting and glucose-y ones to begin with.

On my home OGTT (pure glucose, so no slow digestion involved) I peaked at just under 2 hours.

The reason we test at 2 hours is that you should be on the way back down at that point. A non-diabetic would be most of the way back down, probably about 90% of the way back to where they started. As others have said, though, what time you peak can vary based on what you ate. In general, diabetics peak later than non-diabetics.

If you are curious, try eating one of your typical meals and then test every 15 or 30 minutes for 4 hours. That will tell you where your peak is, at least for that meal. It may vary for different meals. In my case, I don't think it matters much. I peak between 1.5 and 2 hours.
