    • A method for the detection and/or visualization of particle agglutination in a particle suspension is provided, comprising placing a volume of the particle suspension and a volume of a solution or suspension containing an agglutinating agent at substantially the same selected location on a surface of a filter constructed so as to permit passage of individual unagglutinated particles in a direction perpendicular to the surface. A wash solution at optionally placed at substantially the same location as that of said agglutinating agent, and the surface is observed for the presence of particles. There is also provided a method for detection of agglutination reactions, such as used in blood grouping, reverse grouping and cross-matching. A device and a kit based on the invention is also claimed, which facilitates blood grouping, reverse grouping and matching in non-laboratory environment without the need for laboratory instruments.
    • 提供了用于检测和/或可视化颗粒悬浮液中的颗粒凝集的方法,包括将体积的颗粒悬浮液和一定体积的含有凝集剂的溶液或悬浮液放置在基本上相同的选定位置的 过滤器被构造成允许单个未凝集的颗粒在垂直于表面的方向上通过。 任选地在与所述凝集剂的位置基本上相同的位置处的洗涤溶液,并观察表面存在颗粒。 还提供了用于血液分组,反向分组和交叉匹配中使用的凝集反应检测方法。 还要求保护基于本发明的装置和试剂盒,其不需要实验室仪器便于非实验室环境中的血液分组,反向分组和匹配。
