: This test should be measured to establish the pathogenesis of fasting hypoglycemia. The NACB guidelines suggest that there is no role for routine insulin in most diabetic patients. Diabetes Care 34:e61-e99,2011. Patients receiving insulin therapy may develop anti-insulin antibodies which could interfere with the assay. This assay shows nearly equimolar cross reactivity (75-150%) with recombinant human insulin (Actrapid and Humulin) and nsulin analogs (detemir, aspart, glargine and lispro).
: Fasting specimen. Non fasting specimens are acceptable for special studies.
