Claim 0:
1. A system for performing an assay capable of detecting an analyte in a biological sample, the system comprising:
a cartridge comprising:
a plurality of reagent units, wherein one or more of the plurality of reagent units are configured to store cartridge reagents, and
a sample vessel configured to receive the biological sample;

an assay assembly comprising:
an addressable assay unit configured to receive the biological sample and to receive a first cartridge reagent from a first reagent unit of the plurality of reagent units of the cartridge,
a reaction site arranged on an interior surface of the addressable assay unit, wherein the reaction site comprises an immobilized binding reagent configured to bind with the analyte, and
an assembly tip in fluid communication with the addressable assay unit and comprising an opening, wherein the assembly tip is configured to place the addressable assay unit in fluid communication with the first reagent unit or the sample vessel of the cartridge; and

a reader assembly configured to receive the cartridge and the assay assembly, wherein the reader assembly comprises:
an automated fluid transfer device configured to move the assay assembly relative to the cartridge to selectively place the assembly tip of the assay assembly into the sample vessel or into the first reagent unit of the plurality of reagent units and to sequentially transfer the biological sample and the first cartridge reagent into the addressable assay unit via the assembly tip such that a reaction occurs that yields a signal indicative of a presence of the analyte, and
a detection assembly configured to detect the signal indicative of the presence of the analyte.
