Test Number Components Reference Interval
0099228Insulin Antibody Effective May 21, 2012

0.0-0.4 Kronus Units/mL
2001771Glutamic Acid Decarboxylase Antibody 0.0-5.0 IU/mL
0050202IA-2 Antibody 0.0-0.8 Kronus Units/mL

Interpretive Data: The Insulin Antibody assay quantitatively measures human serum autoantibodies to endogenous insulin or antibodies to exogenous insulin.   
Note: If either Insulin Antibody or Glutamic Acid Decarboxylase Antibody is negative, then IA-2 Antibody will be added. Additional charges apply.

Insulin Antibody: Kronus Units are arbitrary. Kronus Units = U/mL
CPT Code(s): 86337 ANTI-INS; 83516 GAD-AB; if reflexed, add 86341 IA-2 Antibody
