Hi @Terry4: Oh, a complicated question. Yes, ~10% of “Type 2s” are autoantibody positive and actually have Type 1. It was 11% in the first study published on the matter, in 1977, the Accord Study had 10%, and so many subsequent studies have found the same thing. And ~10% of women with gestational diabetes are autoantibody positive as well. And no, I am not aware of any professional or organization that is working to change this, and as you know, I study this quite a bit. I myself have been slowly working on the problem for years, but of course I am “just” a patient with T1D, and I work full time and have a life! The Diabetes Forecast articles came out after I wrote to the editor, Kelly Rawlings, and asked her to research/write about misdiagnosis. But unfortunately, the American Diabetes Association has not done much to change and still promotes wrong information about Type 1 diabetes (ADA’s website says, "Type 1 diabetes is usually diagnosed in children and young adults, and was previously known as juvenile diabetes. Only 5% of people with diabetes have this form of the disease). Of course, it’s people of all ages who are diagnosed with Type 1, and it certainly isn’t 5% if 10% of Type 2s actually have Type 1. So Terry, my plan is to retire in a few years and devote myself to this problem in a more systematic way!
