Patent ID: 7256053

Claim:
A device of the type useful to perform a lateral flow immunodiagnostic assay for one or more target analytes, the device comprising: (a) a carrier for conducting the flow of sample along a path, the carrier comprising: a sample receiving zone comprising a detectably labeled, mobile detector reagent for binding to the target analyte, and an analyte detection zone downstream of the sample receiving zone and comprising an immobilized capture reagent for capturing a complex formed by said analyte and said detector reagent, and (b) a housing for receiving the carrier, the housing comprising a sample receiving system and a sample deposition system in flow communication with the sample receiving system and the carrier, wherein the sample deposition system delivers sample from the sample receiving system onto the carrier as a sample band that is essentially linear and has a width greater than the width of the analyte detection zone, the width being transverse to the path of sample flow.
