diagnosed in 2004, as an adult in France
Went to doc . Symptons,; weight loss, drinking/urinating , thrush over a period and what sent me to the doctors that day was frightening breathing problems whilst trying to exercise. This was my first visit to him and he didn't know me at all. He seemed sceptical when I said I thought I could have diabetes.... too old for type 1, thin for type 2, but most of the symptoms had been present for some time
GP sent me for fasting blood test next morning,told me if the result was over 126mg/dl (7mmol)to come back to him. ( copies of results are sent direct to patients here )
Fasting glucose was 396mg/dl, (22mol); result faxed to him ,he called me back, phoned hospital spoke to consultant whilst I was there who said I should go straight to the hospital emergency dept.
Met by consultant who took an armfull of blood and then put me on an insulin pump.
Stayed in hospital for 10 days whilst tested for everything.
Tests specifically to do with type 1 diagnosis were C peptide and several antibody tests.(ICA, IA2, GAD, IAA) also a whole raft of others : 24hr urine test/echograph on kidneys, heart, ct scan, exercise stress test, are those I can remember, presumably to exclude other reasons for diabetes and check I hadn't developed any other problems. In the couple of weeks after leaving hospital I also had a retinal check and an echograph on my arteries.
Consutant diagnosed type 1, but from what I have read since it is probably LADA, A form of type 1 in older people where the loss of beta cells is slower than in classic childhood type 1
I have read many times on this forum and others of people with similar histories and similar fasting glucose levels who are sent away from GPs surgeries with a prescription and no futher tests.... some of these are misdiagnosed. I was very lucky to be in a place where full investigations are the norm.
