• Use to determine presence of antibodies to exogenous insulin analogues. Testing not recommended for patients receiving insulin >2 weeks, as insulin antibody formation may occur.
• 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), Islet Cell Cytoplasmic Antibody, IgG (0050138), and Zinc Transporter 8 Antibody (2006196).
• Do not use to differentiate type 1 versus type 2 DM, for most cases.
