This test is intended to be used to detect antibodies to insulin that are present in sufficient quantity to possibly affect diabetes control.
It is not intended for the detection of insulin autoantibodies (IAA).

Interpretation
Detects insulin antibodies that have a binding capacity similar to or greater than endogenous insulin levels. Cannot detect or rule out IAA (insulin autoantibodies) as these, if present, are usually at much lower concentrations.
Reference Intervals
Given with result (depends on free insulin concentration).
Test Method
Roche Elecsys assay of insulin in raw and PEG extracted plasma.
