Hi Kenny,
Lots of questions
so I will take them one by one.
Sadly, lab test results do go pearshaped, It may be an error in labelling, or contamination, or absent mindedness, but people are people, and that means they are fallible. Sad but true. But they just run them again - so long as someone notices. This time, you did, so well done on spotting the error and chasing it.
The real reason that the NHS doesn't supply meters to many T2s is that they want to save money. They argue a lot of things - it hurts the fingers, it doesn't tell you anything unless you are on insulin, it isn't policy, they argue there is no proven benefit, yada, yada - but the truth is that the NHS is strapped for cash and giving meters and expensive test strips to T2s is (in their opinion) less of a priority that we (the T2s) would like it to be.
So your two nurses gave you two different answers because they were trying to dodge the 'we aren't prepared to spend that money on you' conversation. Plus, of course, they may actually believe what they are saying. After all, if they have never seen a T2 take dietary control, reduce their HbA1c and maintain the improvements, then they have never, personally seen any benefit to handing out a meter...
Don't worry about the risk of contamination from a second hand meter. They would never hand out a second hand meter for precisely that reason. It is against the rules. If you ever do get given one, it will be new and straight from the packaging. The meters themselves are often given away by the meter manufacturers, because they want to give them away so that people keep coming back and spending dosh on repeat orders of the test strips. That is where they make their profits.
Personally, I have had a meter for approx 4 years now. Wouldn't be without it. And I absolutely know that it is the best and most important reason that I have control over my T2 diabetes. Without it, I wouldn't know that I can eat a few chips and have good blood glucose, but that bread sends my bg sky high. And I wouldn't know that I can eat a whole punnet of delicious juicy fresh cherries, so long as I
spread them across the day, whereas eating them all at once would give me horrible bg readings. I find my meter invaluable for portion size and food choices. Wouldn't ever want to be without it.
