Hi Jim! I think you should ask your endo for additional antibody testing. There are several antibodies that can predict your risk for type 1: GAD, Znt8, ICA, and IA-2. Testing positive for just GAD with normal A1c does not indicate a type 1 diagnosis, it shows you are at an increased risk for developing type 1 (but does not guarantee that you will ever get type 1). Testing positive for 2 or more antibodies indicates that you will at some point in your life get a type 1 diagnosis. I’ve been GAD positive for 8 years now and just learned that I am positive for a second antibody, meaning I will develop type 1 in the next few years or so. You can google “type 1 staging” for more info on the antibodies!
Thank you Anna…that is very helpful information!
