BLOOD TYPE METHOD SYSTEM AND DEVICE

摘要

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.
