Are you sure you didn't have anything on your hand when you tested? Hand lotion, for example, can cause a false high reading.
Just something to consider.
Thank you for your responce. I guess I am just over reacting.
Thanks for your time.
Well good that you ruled out diabetes by going to the doctor. Did you go to an endocronologist? Did you ask the doctor the same question you are asking the forum?
I do know that blood sugars go up and down all day in a non-diabetic(not too high or too low, but they do fluctuate.)
It sounds as if you did everything you should have. How do you feel? Did you notice anything about your health before the class and blood sugar readings? Maybe you are overthinking-you went to the doctor and he/she told you by the tests that your readings are fine. If you used a glucometer in your class they can be off by a 20% range.
