Abstract
A device for a self contained solid phase immunodiffusion assay. The device is comprised of a sample collector, a tube with compartmentalized reagents and a ligand receptor capture membrane filter area. The seals can be broken through pressure on the sample collector. The sample collector is pushed through the seals, mixed with reagent, and then pushed into a ligand receptor reaction area wherein the tip of the sample collector contacts diffusable membranes or filters and transfers the reactants to a capture membrane wherein a ligand receptor reaction can be visualized by the naked eye.
