Immunoassay testing kit and containers
First Claim
1. A testing kit for use in an immunoassay testing device that detects a binding reaction between a pair of first and second substances, particularly biogenic substances, which specifically bind together allowing deposition of electrically conductive particles which fully or partially complete an essentially open electrical circuit, said device having a conveying mechanism with a plurality of predetermined container positions, said kit comprising:
- a first container receivable by said conveying mechanism having a plurality of cavities for receiving fluids, at least one of said fluids is one of said substances;
at least one second container receivable by said conveying mechanism to be displaced along said axis of motion of said conveying mechanism, said second container having a cavity and having electrical contacts for engagement from above when fit in said conveying mechanism, said electrical contacts being open ends of said circuit;
whereby, said testing device transfers at least one of said fluids from said first container to said second container causing a binding reaction in the presence of said other substance.

Abstract
A kit for use in an immunoassay testing device that detects a binding reaction between a pair of first and second substances, particularly biogenic substances, which specifically bind together allowing deposition of electrically conductive particles which fully or partially completing an essentially open electrical circuit. More particularly, the kit provides self contained reagent and testing packages that are less contaminant prone and subject to minimal waste. The kit has a self contained reagent package and a test cartridge that are accessible by the testing device. The reagent package has cavities for reagents and diluting fluids. The test cartridge has a cavity for the test specimen and circuitry that is closed upon deposition of electrically conductive particles following the binding reaction.
