Methods for determining the presence and/or concentration of an analyte in a biological fluid sample are disclosed. The methods generally include admixing in solution certain polymer/reactant and reporter/reactant conjugates along with the biological fluid sample suspected of containing the analyte, thereby forming ternary complexes. The separation of the complexes from the reaction mixture is achieved through the affinity of certain selected polymer compositions for various solid phases. Upon separation, the amount of reporter activity in the solution may be measured, and therefrom the presence and/or concentration of the analyte determined. Multiple analyses on a biological fluid sample suspected of containing one or more analytes may also be performed, using either a variety of different reporters or selected polymers having varied affinity for the solid phase.

本发明公开了测定生物液体样品中分析物存在和/或浓度的方法。这些方法一般包括在溶液中将某些聚合物/反应物和报告物/反应物共轭物与疑似含有分析物的生物液体样品混合,从而形成三元复合物。通过某些特定聚合物成分对各种固相的亲和力,可将复合物从反应混合物中分离出来。分离后,可测量溶液中报告活性的量,并由此确定分析物的存在和/或浓度。还可以使用各种不同的报告物或对固相具有不同亲和力的精选聚合物,对疑似含有一种或多种分析物的生物液体样本进行多次分析。
