    • Method and test kit for assaying in a sample an analyte which is a bloodgroup antigen present on erythrocytes or an antibody binding to such a bloodgroup antigen. To that end, the sample is treated with a reagent containing a binding partner for the analyte, so that a complex of bloodgroup antigen present on erythrocytes and antibody bound thereto is formed if the sample contains analyte. The analyte is a bloodgroup antigen present on erythrocytes, the analyte binding partner is an antibody capable of binding to the bloodgroup antigen and if the analyte is an antibody binding to a bloodgroup antigen, the analyte binding partner is the bloodgroup antigen present on erythrocytes. Erythrocytes, complex or non-complexed, are then separated from non-bound antibodies using a separation medium with a density higher than that of the liquid containing the antibodies but lower than the density of crythrocytes. Complexed erythrocytes are separated from non-complexed erythrocytes by binding complexed erythrocytes to a solid surface on which an immunoglobuilin-binding substance is immobilized and discharging non-complexed erythrocytes to a deepened zone of the reaction vessel. The result is then determined by detecting where the erythrocytes are located.
    • 用于在样品中测定作为存在于红细胞上的血型抗原或与这种血型抗原结合的抗体的分析物的方法和测试试剂盒。 为此,用含有分析物的结合配偶体的试剂处理样品,使得如果样品含有分析物,则形成存在于红细胞上的血型抗原与其结合的抗体的复合物。 分析物是存在于红细胞上的血型抗原,分析物结合配偶体是能够结合血型抗原的抗体,如果分析物是与血型抗原结合的抗体,则分析物结合配偶体是存在于红细胞上的血型抗原。 然后使用密度高于含有抗体但低于冷冻细胞密度的密度的分离培养基,将来自复合物或非络合物的红细胞与未结合的抗体分离。 通过将复合的红细胞与固定有免疫球蛋白结合物质的固体表面结合并将非络合的红细胞排出到反应容器的加深区域,将复合红细胞与非复合红细胞分离。 然后通过检测红细胞位于何处来确定结果。
