Ordering Recommendation
If pursuing antibody testing to determine autoimmune diabetes mellitus, perform at least 2 antibody tests. Other antibody tests include Glutamic Acid Decarboxylase Antibody (2001771), IA-2 Antibody (0050202), Insulin Antibody (0099228), and Islet Cell Cytoplasmic Antibody, IgG (0050138).
Most useful to establish autoimmumne etiology in previously diagnosed type 1 DM.
Do not use to differentiate type 1 versus type 2 DM, for most cases.
