How is that denying it? And for your info people are told not to do exercise etc as it can make blood sugar levels rise in the short term, not fall! So if anything, by doing normal housework it should of raised the result not lowered it!
I drink very little usually so in the first test I was probably dehydrated which would of made the reading higher too.
At the end of the day there is no way to trick the test, it will either tell you you have it, or you don't, but making sure you get a fair result by keeping well hydrated, trying not to get stressed before the test, ensuring you get a good nights sleep, not smoking etc etc will all help to get a true reading.
Also I found it shocking how "out" the monitoring strips are- 5mins before the first blood test I did it and 5mins before the last test and my numbers were 3.7 on glucose monitor, but 4.5 on the blood test and 6.7 before the second but 4.7 on the blood test, that's quite some inaccuracy!
Btw I found it was a lot more involved than "just low carbing" and no sugar, it really requires some serious reading up on stuff as normal foods that are reasonably healthy can shoot up your blood sugars like white pasta, white rice, pretty much every cereal out there(bran has the lowest gi). We were told at the diabetic clinic to watch the glycemic index of foods but to not get too obsessed with it and to ensure all meals contained a small amount of low gi carbs.
I have a new found respect for diabetics now as its not straightforward or easy in the slightest!
