What levels would you normally expect to see? Have you been eating anything different? Any change of medication? It's not unusual for blood sugar to go off balance if unwell. Are you sure the meter is working? Test strips ok?
It's probably worth also be worth asking
@AnnBlanking how long she has been a diabetic and how well the blood sugars have been until this point?
@AnnBlanking, you're really not wanting BGL's that high for a prolonged period of time, in fact - at all.
If you read these replies and you've not got your blood sugars back in range - I'd head straight to your GP/nearest clinic to get seen to. Not to scare you, but at thoses levels you're in real danger of DKA and other nasty problems which you really don't want to be part of.
Hope to hear from you soon and take care.
