Sorry, perhaps I should have explained more? My point iwas to rule out Type 2, if you have diabetic antibodies then you are not not Type 2 but many of the initial symptoms are common between both 1 and 2.
Seriously – to be wrongly diagnosed is lethal! Every organ is damaged in my case. I can only comment on my own experience but I can't be alone!
The full blood test covers 4 level tests.
Because of my own personal wrong diagnosis by my previous diabetic team, this has caused major body damage, I became a qualified professional in Diabetic Management because of this and as you say correctly there are many variables within test results, correct full blood tests covers at least 4 different tests.
At my last count there were 10 types of diabetes!
My point is that the errors made by general questions by GPs; Family history, your weight, lifestyle... instead of medical tests. In essence they look at you. “Like a Carry On film, "you're A1’. It should be based on a full scan with blood rests.
Diabetes is of course an ongoing issue, I read the other day that type 1 is caused (could be) by a virus and not genetic?
In my case not genetic...
I think the issue is that, allegedly, 90% of those diagnosed with diabetes have T2. The balance 10% will include those immediately diagnosed T1, gestational, Steroid induced/T3c etc, so the wider testing would be a catch-all for a modest number.
Now, please, PLEASE don't think I am saying that modest balance is unimportant. Of course, it is important, but no system is ideal. Were it ideal, every person presenting with a bit of a cough would be referred for a high resolution CT scan, or those with tummy ache, an MRI, with contrast.
I also know that CT and MRI are more costly that most blood work, but in my experience of process improvement, per se, and statistics, the target is usually somewhere on 80/20. As I say, not ideal, but with SO many issues facing our health systems, and the public purse in general, unless we move over onto an insured system, we will not achieve as you wish.
Having lived in places where insurance, or deep pockets are the answer to medical bills, I know where I will take my compromises. (All of that said, in the spirit of full disclosure, I have had private consultations where I have felt the NHS response was not enough for my needs and wants.)
