1. A system comprising a reader for analyzing one or more analytes in a fluid sample, the reader comprising:
a casing comprising at least one port into which a cartridge comprising an immunoassay device with multiple parallel immunoassay channels may be inserted;
a holster which receives and positions the cartridge within the reader;
an optical system comprising:
excitation optics comprising multiple light sources and an excitation lens to direct light from each one of the multiple light sources to a corresponding individual excitation area upon a different immunoassay channel when the cartridge is positioned within the holster; and
collection optics comprising multiple photosensors and a collection lens to collect light emitted from each one of the individual excitation areas and direct the collected light towards a corresponding photosensor;
an electromechanical motor system to move the holster, with the cartridge positioned therein, to interrogate different regions along each of the multiple immunoassay channels; and
one or more digital processors and associated electronics to receive data from and control the optical and electromechanical motor systems,
wherein the casing contains the holster, the optical system, the electromechanical motor system and the one or more digital processors and associated electronics.
