Your assuming that I understand what I just wrote
Type 1 is assumed to be an autoimmune response where your body attacks itself, and specifically the pancreas.
To determine Type 1 they usually test you for antibodies. I was tested for GADA and ICA because I didn't fit the ideal Type 2 model (essentially negative on both).
But what that report said was that sometimes people are not identified as Type 1 because there are other antibodies that are not tested for or not discovered yet. One of which is this newly discovered (hah, I can find a reference in 2009) Zinc 8.
