Ordering Recommendation

Determine presence of antibodies to endogenous or 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 (DM), perform at least two antibody tests. In most cases, use glutamic acid decarboxylase antibody in combination with another antibody test. Other antibody tests include Islet Antigen-2 (IA-2) Autoantibody (3001499), Glutamic Acid Decarboxylase Antibody (2001771), Islet Cell Cytoplasmic Antibody, IgG (0050138), and Zinc Transporter 8 Antibody (2006196). Do not use to differentiate type 1 DM from type 2 DM, for most cases.

0.0-0.4 Kronus Units/mL

Interpretive Data

A value greater than 0.4 Kronus Units/mL is considered positive for Insulin Antibody. Kronus units are arbitrary.
Kronus Units = U/mL. 

This assay is intended for the semi-quantitative determination of antibodies to endogenous insulin or antibodies to exogenous insulin in human serum. Antibodies to exogenous insulin therapies may be detected using this method. The magnitude of the measured result is not related to disease progression. Results should be interpreted within the context of clinical symptoms.
