  • Publication number: 20200363434
    Abstract: Blood typing systems and methods are provided. In one embodiment, the method may be achieved by applying a sample to a surface of a substrate having one or more binding agents immobilized thereon, wherein the one or more binding agents are capable of binding to one or more substances in the sample; substantially removing unbound material from at least a portion of the substrate having immobilized binding agent; and detecting substances bound to the one or more binding agents immobilized on the substrate; wherein the applying the sample to the surface of the substrate step is concurrent with the removing unbound material from at least a portion of the substrate step. Systems and other methods are also described and illustrated.
