Lateral flow assay devices for use in clinical diagnostic apparatus and configuration of clinical diagnostic apparatus for same

Abstract

A lateral flow device for use in a mainframe or point-of-care clinical analyzer, in which the lateral flow device includes a planar support having at least one sample addition area and at least one reaction area disposed thereon. The sample addition area and reaction area are fluidly interconnected to one another and form at least one lateral fluid flow path. The lateral flow device is sized for retention within a storage cartridge of the analyzer defined by a hollow interior and having a plurality of lateral flow assay devices retained in stacked relation therein.

Description

[0001] Cross References to Related Applications [0002] This patent application is a provisional application filed pursuant to the relevant paragraphs of 35 U.S.C. §111 and 37 CFR §1.53. technical field [0003] This patent application relates generally to the field of analytical chemistry, and more particularly to lateral flow assay devices allowing their use in conjunction with automated clinical diagnostic equipment, and supporting lateral flow assay devices to allow their cooperative testing (alone, or with other Analytical test elements and chemical systems combined) automated clinical diagnostic equipment. Background technique [0004] Current automated laboratory instruments for the analysis of immunoassays are relatively complex, difficult to use, have lower reliability than their general chemical counterparts, and have high production costs since assay processing often requires many mechanisms. These assay processing mechanisms include: those associated with wet r...

Problems solved by technology

[0009] As noted, the use of so-called "wet" chemistry techniques for conducting and detecting immunoassays, while offering good throughput and satisfactory test results, is relatively limited due to the overall expense and complexity involved
