Title: | Automated immunoanalyzer system for performing diagnostic assays for allergies and autoimmune diseases |
Abstract: | A quantitative method for performing an automated diagnostic assay, comprising: incubating a capture reagent with a streptavidin-coated medium to form a solid phase complex; washing the solid phase complex to remove excess capture reagent; incubating the solid phase complex with a serum sample to form an immune complex; washing the immune complex to remove any unbound sample; incubating the immune complex with a conjugate to create an immune-conjugate complex; washing the immune-conjugate complex to remove any unbound conjugate; introducing a substrate capable of generating a quantifiable response; and calibrating the response generated from introducing the substrate. |

Assignee: | Hycor Biomedical, LLC (Indianapolis, IN) |
Application Number: | 14/215,720 |
Patent Claims: | 1. A quantitative method for performing an automated diagnostic assay, comprising: dispensing a quantity of streptavidin-conjugated universal fluorescent-labeled magnetic
microparticles into a reaction cuvette within a reaction rotor of an immunoanalyzer instrument using a first pipettor; measuring a first fluorescent signal associated with the quantity of streptavidin-conjugated universal fluorescent-labeled magnetic
microparticles through an optics pipette; selecting a capture reagent suitable for performing the diagnostic assay; dispensing the capture reagent into the reaction cuvette using the first pipettor; incubating the capture reagent with the quantity of
streptavidin-conjugated universal fluorescent-labeled magnetic microparticles to form a solid phase complex in the reaction cuvette; washing the solid phase complex to remove excess capture reagent; dispensing a serum sample into the reaction cuvette
using a second pipettor; incubating the solid phase complex with the serum sample to form an immune complex; washing the immune complex to remove any unbound sample; dispensing a conjugate into the reaction cuvette using a third pipettor; incubating
the immune complex with the conjugate to form an immune-conjugate complex; washing the immune-conjugate complex to remove any unbound conjugate; introducing a substrate capable of generating a quantifiable response using the third pipettor;
transferring the substrate and immune-conjugate complex from the reaction rotor to an optics box using the optics pipette by aspirating the substrate and immune-conjugate complex from the reaction cuvette into the optics pipette; measuring a second
fluorescent signal associated with the transferred material through the optics pipette and calculating a ratio of the first fluorescent signal to the second fluorescent signal to obtain a bead retention ratio; measuring a chemiluminescent signal in the
transferred material; determining the response generated from introducing the substrate; and adjusting the quantifiable response for bead retention by: adjusting the quantified chemiluminescent signal by the bead retention ratio to calculate a reported
value; wherein one or more of the washing steps include washing the solid phase, immune, and/or immune-conjugate complexes by magnetically sequestering the solid phase, immune, and/or immune-conjugate complexes being washed within a confined area of a
reaction cuvette; wherein the step of incubating the capture reagent with the streptavidin-conjugated universal fluorescent-labeled magnetic microparticles comprises incubating the streptavidin-conjugated universal fluorescent-labeled magnetic
microparticles with a biotinylated capture reagent; wherein the step of incubating the capture reagent with the streptavidin-conjugated universal fluorescent-labeled magnetic microparticles includes incubating the capture reagent that is retained in a
suspension by a reagent diluent comprising about 25% human serum albumin (HSA); wherein the step incubating the immune complex with a conjugate comprises incubating the immune complex that is retained in a suspension by a conjugate diluent comprising
about 2-5% polyethylene glycol; and wherein horseradish peroxidase (HRP) is used as an indirect label when washing the immune complex to remove unbound sample.
2. The method of claim 1, wherein the step of incubating the solid phase complex with the serum sample comprises binding an allergen-specific human immunoglobulin E (IgE) present in the serum sample to a biotinylated capture reagent. 3. The method of claim 1, wherein the step of incubating the solid phase complex with the serum sample comprises binding an autoimmune-specific human immunoglobulin G (IgG), an autoimmune-specific human immunoglobulin M (IgM) or an autoimmune-specific human immunoglobulin A (IgA) present in the serum sample to a biotinylated capture reagent. 4. The method of claim 1, wherein the capture reagent is derived from the biotinylation of a purified allergen, protein, enzyme or antibody. 5. The method of claim 1, wherein the capture reagent is derived from the biotinylation of an allergen extract comprised of a multiplicity of allergens. 6. The method of claim 1, wherein the capture reagent exists as an amalgam of multiple biotinylated capture reagents selected from purified allergens, proteins, enzymes, antibodies and allergen extracts. 7. The method of claim 1, wherein the step of transferring the substrate and immune-conjugate complex to the optics box comprises using an automated pipette arm with a reusable optics pipette tip to aspirate the sample. 8. The method of claim 1, further comprising entering the first and second fluorescence signals and chemiluminescence signal into an algorithm to generate a bead retention adjusted relative light unit signal. 9. The method of claim 8, further comprising comparing the generated bead retention adjusted relative light unit signal to a calibration curve relative light unit signal. |
