have you had a cpeptide test recently?
There was a very interesting study done in Scotalnd where they tested cpeptide on all their long standing T1s
and found that 13% had significant levels of cpeptide.
Serum C-peptide testing was performed in 859 individuals (90% of the eligible cohort), of whom 114 (13.2%) had C-peptide ≥200 pmol/L. The cause of diabetes was reclassified in 58 individuals (6.8% of the tested cohort). The majority of reclassifications were to type 2 diabetes (44 individuals; 5.1%), with a smaller proportion of monogenic diabetes (14 individuals; 1.6%). Overall, 13 individuals (1.5%) successfully discontinued insulin, while a further 16 individuals (1.9%) had improved glycaemic control following the addition of co-therapies.
So a small but significant (specially if you are one of them) number of T1s do get misdiagnosed...
The other question I have is what happens to your blood sugars when you get ill? Do you have to worry about DKA or do your bgs stay low?
The more I read about diabetes the more I find out that people's metabolisms are different, even when they have the same "Type", but I'd want to be very careful about promising an insulin free existence to more than a very few (possibly misdiagnosed) T1s.
