摘要： The present invention provides a method of pretreating a specimen, which allows measurement according to an immunoassay to be carried out on a specimen from nasal secretion while preventing non-specific reactions. According to this method, the specimen from nasal secretion is treated with a protease beforehand and then an immunoassay is performed. As the protease, it is preferable to use semi-alkaline protease (EC 3.4.21.63). Furthermore, it is preferable that a substance to be pretreated by the pretreatment method according to the present invention is an influenza virus contained in the specimen from nasal secretion. The immunoassay preferably is an immunoagglutination assay. Examples of the immunoagglutination assay include a turbidimetric immunoassay, a latex turbidimetric immunoassay, and a latex agglutination assay that is performed on a slide glass.

摘要： In an immunoassay method using an antibody sensitization particle, the occurrence of false positives is prevented. The immunoassay method of the present invention is an immunoassay method for detecting or quantifying an analyte in a specimen by mixing an antibody sensitization particle obtained by sensitizing a particle with an antibody that reacts with the analyte in the specimen with the specimen, and measuring agglutination of the antibody sensitization particle by an antigen-antibody reaction, and the method includes pre-treating the specimen by using a cation exchange material in advance of the mixing step. As the cation exchange material, for example, a cation exchange material having a sulfonic acid group or a carboxyl group as a functional group can be used, and a form thereof is not limited particularly, and may be, for example, a cation exchange filter, a cation exchange column or the like.

A sample solution is supplied to the sample supply portion 13, and a developing solution is supplied to the developing solution supply portion 12 simultaneously with the supply of the sample solution or prior to the supply of the sample solution. By the development of the developing solution in the development member 11 in the presence of a labeled specifically binding substance 15, the sample solution is introduced to the detection portion 14. In the detection portion 14, a complex 18 of the immobilized specifically binding substance 17, the analyte 16, and the labeled specifically binding substance 15 is formed. The analyte 16 is analyzed by detecting a label 19 in the complex 18.
