High blood sugar

What have you already done?

I've just looked back through your posting history and you haven't really told us anything about yourself.

You just seem to pop up every 4 weeks or so with a similar question, and no feedback about what you did and if it fixed the problem.

So - are you on insulin?
If so, what regime?
When did you test - before or after a meal?
What have you been eating?
What other medications are you on?

The answer to "what should I do" is "give us some information to work on".

Have you checked again to see if it is still going up?

Edit: Oh, and what tablets in what dosage? What type/brand of insulin? Do you take insulin once a day or do you take some with each meal?

To add to the questions from @LittleGreyCat, I would also ask if you have tried washing your hands and doing another tests.
One unexpected reading may be due to your meter having a wobbly or picking up some sugar from your finger ... newspaper print, for example, can affect your BG.
