Hi,
My girlfriend bought a glucometer yesterday to follow a caloric restriction program. As my mother had type 1 diabetes, I know those machine quite well. I took a test to show her how it works and I was stunned to see the results. I'd expected to see something along 3 to 4 mmol/L. as it was in the morning before breakfeast but I had 7.7 mmol/L (that would be 138.6mg/dl or 1.386g/l).
I know for a fact that this is a higher then normal. It was in the morning, The only thing I had for the preceding 12 hours was a coffee (35-45 minutes before the test was taken) with less the 1 teaspoon (< 5g) of sugar in it.

I've seen my mother suffer from this disease for so long that I might be over-reacting. Nevertheless, i'm truly woried about this results.

Should I be worried? Should I talk to my doctor about it?

Thanks in advance for your answers.
