Serum insulin immunoassays and relevant issues / 中华内分泌代谢杂志

Serum insulin immunoassay plays an important role in the investigation of glucose metabolic disorders. Insulin assay has undergone method innovations for 50 years. Diverse insulin molecular immunogenicity and multiform biological activities, in addition to the immunoassay complexity, make serum insulin assays practically interfered by the factors such as blood sample qualities, serum anti-insulin antibodies and immunological cross-reactivity. Meanwhile, lack of standardization has imposed obstacles in the comparative studies among different reference laboratories.
