    Abstract: A semi-automated biological sample analyzer and subsystems are provided to simultaneously perform a plurality of enzyme immuno assays for himan IgE class antibodies specific to a panel of preselected allergens in each of a plurality of biological samples. A carou­sel is provided to position and hold a plurality of reaction cartridges. Each reaction cartridge includes a plurality of isolated test sites formed in a two dimensional array in a solid phase binding layer con­tained within a reaction well which is adapted to con­tain a biological sample to be assayed. The carousel and cartridges contain structures which cooperate to precisely position the cartridges in each of three separate dimensions so that each cartridge is posi­tioned uniformly. An optical reader operating on a principle of diffuse reflectance is provided to read the results of the assays from each test site of each cartridge. Also provided is a subsystem which provides predetermined lot-specific assay calibration data which is useful for normalizing the results of various assays with respect to predetermined common standard values.

    Abstract: Disclosed is an analyzer for determining the presence, absence or amount of an analyte in a sample, wherein the analyzer comprises: (a) an electromagnetic radiation source (301) that emits electromagnetic radiation that defines an interrogation space comprising a focused spot of a beam from the electromagnetic radiation source (301); (b) a capillary flow cell (313) for passing a sample through the interrogation space; (c) a source of motive force for moving the sample in the capillary flow cell (313); (d) an electromagnetic radiation detector (309) operatively connected to the interrogation space that detects photons emitted from the interrogation space during a plurality of bins; and (e) a processor (310) operatively connected to the detector (309), wherein the processor determines the presence, absence or amount of an analyte in a sample by:
    (i) determining a threshold photon value corresponding to a background signal in the interrogation space, (ii) determining the presence of a photon emitting species comprising or corresponding to the analyte in the interrogation space in each bin of the plurality of bins by identifying bins having a photon value greater than the threshold value, (iii) comparing the number of bins having a photon value greater than the threshold value to a standard curve that is generated using one or more samples of known standard concentrations.
