Abstract
A measurement method and a measurement reagent for thyroglobulin, which enable measurement of a more accurate amount of thyroglobulin by a single test without being influenced by interference of anti-thyroglobulin antibody, are disclosed. The measurement method for thyroglobulin, wherein thyroglobulin in a sample separated from a body is measured by an immunoassay, includes a pretreatment step of mixing the sample separated from a body with a pretreatment liquid containing one or both of a surfactant and an acidifier. The reagent for immunoassay of thyroglobulin includes a pretreatment liquid containing one or both of a surfactant and an acidifier.
Claims17
A method of measuring, by immunoassay, thyroglobulin in a sample separated from a body, the method comprising (a) a pretreatment step of mixing the sample separated from a body with a pretreatment liquid to produce a pretreated sample, said pretreatment liquid containing an acidifier or an anionic surfactant, wherein when the pretreatment liquid contains an acidifier, the pretreatment liquid further contains a cationic surfactant, and (b) subsequently mixing said pretreated sample with a buffer containing a water-soluble polymer.
