Method for suppressing abnormal detection in immunoassay in automatic analysis device, and immunoassay reagent

摘要

In the immunoassay method using an automatic analyzer, the reaction cuvette is of a disposable type or a reuse type, and the optical detection method suppresses the occurrence of abnormal detection values regardless of transmitted light or scattered light, so that it has good reproducibility. An object of the present invention is to provide a method for measuring and an immunoassay reagent used in the method. A method for suppressing occurrence of abnormal detection values and improving measurement reproducibility, comprising adding polyethylene glycols having a weight average molecular weight of 300 to 3000 in an immunoassay reagent.
