Thanks for the warm welcome!
I say suspected because the doctors and nurses haven't come up with anything more specific than that!
I was diagnosed because I was losing weight without trying. My GP referred me to a diabetic nurse and when I saw her she checked my blood glucose and it was 27. I didn't have any ketones so she said I was Type 2 but put me straight on insulin to bring my levels down. Then I saw another nurse who said that I didn't fit the profile for Type 2 so I must be Type 1.
I requested the blood test to find out which type I am and was told I'd get the result in two weeks. That passed and they kept fobbing me off until I found out that actually the doctor who sent me for the test is Spanish and had requested the test (is it GAD antibodies or something?) with a Spanish name. The lab didn't know what she meant and forgot about it.
Then a specialist at the hospital chased the test up for me and it came back negative ie no antibodies therefore Type2. However the next specialist I saw said that the lab probably just used the latest blood sample they had rather than the one taken at diagnosis so actually the result was inconclusive and he suspects I'm actually Type 1.
So there you go! I've resigned myself to not knowing officially and all the doctors and nurses tell me it makes no difference, I need insulin and that's that.
