ABSTRACT
OBJECTIVE:
To explore the interference of exogenous insulin therapy on insulin detection test by electrochemical luminescence immunoassay (ECLIA).METHODS:
Insulin level was determined by ECLIA. According to the requirements of EP7-A2 of American Society for Clinical Laboratory Standards Institute Standards, paired difference experiment was conducted to evaluate the interference of 8 kinds of exogenous insulin on insulin detection, dose effect experiment was conducted to determine the relationship between exogenous insulin concentration and interference degree.RESULTS:
When the interfering substance concentrations were ≤250 µU/mL, Gansulin Nâ, Gansulin Râ, Humulin Râ,Novolin Râ and Lantusâ all showed linear positive interference, while Levemirâ showed a linear negative interference in high concentrations insulin and non-interfering in low concentrations insulin, Humalogâ and Novo Rapidâ showed non-interference in insulin detection.CONCLUSIONS:
The use of different exogenous insulin may have different interference on insulin measurement, which need laboratorians and physicians notice to avoid misdiagnosis.
