Type 1 High blood sugar!

[lisacp]

Hello can anyone explain this?
I tested my blood at 2pm this afternoon it was 9.2.
I then went on a 3 mile walk with the dogs.
When I got home I shared a can of lager with my husband (not even 1/2 a pint)
I have just tested my blood and it has risen to 17.2
I have not eaten and I have exercised.
Does anyone have any ideas as to why it is so high?
Thanks

I would wash my hands and retest to make sure your second reading is ok.

If the 17.2 was a one-off and your bg is usually fine after exercising then I wouldn't worry about it, as Mike says it could have been a false reading if you didn't wash your hands beforehand.
