    • Method for the determination of an analyte in a volume of a fluid sample, in particular of anti-TSH receptor autoantibodies in a patient serum, in which one or more determination reagent(s) which contains or which contain a) a predetermined amount of a binder (B) for the analyte (A) and b) a predetermined amount of a competitor (K) which is likewise bound by the binder (B), in such a way that the extent of its binding to the binder (B) is correlated with the simultaneous presence of the analyte (A) and/or its amount in the sample, the competitor (K) being labelled, or being capable of being labelled, with a label which permits its qualitative and/or quantitative determination, is or are added to the sample with the formation of a liquid reaction mixture, wherein c) the liquid reaction mixture is reacted simultaneously or subsequently with a solid phase to which a substance (Imm) for the selective immobilization of the amount of competitor (K) not bound to the binder (B) is bound, and optionally with a labelled reactant (Label) for the immobilized competitor (K), and after a quantitative separation of the solid phase from the liquid reaction mixture, the amount of the competitor (K) bound to the solid phase is determined in a manner known per se by means of physical and/or chemical detection of the label bound to said competitor, and the determined amount of said competitor (K) is correlated with the presence and/or amount of the analyte (A) in the original sample.
    • 用于测定流体样品体积,特别是患者血清中抗TSH受体自身抗体的分析物的方法,其中一种或多种测定试剂含有或含有a)预定量的 用于分析物(A)的粘合剂(B)和b)预定量的同样由粘合剂(B)结合的竞争剂(K),使得其与粘合剂(B)的结合程度为 与分析物(A)的同时存在和/或其在样品中的量,被标记的竞争剂(K)或能够被标记的允许其定性和/或定量测定的标记是或 被添加到样品中,形成液体反应混合物,其中c)液体反应混合物同时或随后与固相反应,物质(Imm)用于选择性地固定竞争剂(K)的量不 与粘合剂(B)结合,o 用固定化的竞争剂(K)的标记反应物(Label)分批,并且在从液体反应混合物定量分离固相之后,以已知的方式测定与固相结合的竞争剂(K)的量 本身通过物理和/或化学检测与所述竞争者结合的标签,并且确定的所述竞争者(K)的量与原始样品中分析物(A)的存在和/或量相关。
