1. A device for detecting the presence of at least two analytes in a patient'"'"'s single fluid sample, the device comprising:
- a pipetting station, wherein the pipetting station is configured to receive at least two pipettes, wherein the at least two pipettes comprises a first pipette having a first immobilized binding partner specific to a first analyte present on an inner surface of the first pipette and a second pipette having a second immobilized binding partner specific to a second analyte present on an inner surface of the second pipette, wherein the analyte specificity of the first immobilized binding partner is different than the analyte specificity of the second immobilized binding partner;
wherein the first pipette is disposable within a fluid sample receptacle configured to hold a patient'"'"'s single fluid sample, the first pipette configured to withdraw at least a portion of the single fluid sample into the first pipette such that the first immobilized binding partner is brought into contact with the withdrawn single fluid sample to thereby form a first analyte-binding partner complex if a first analyte is present in the single fluid sample; and
further wherein a non-reacted portion of the single fluid sample is re-dispensable from the first pipette into the fluid sample receptacle, and thereafter the second pipette is disposable within the fluid sample receptacle whereby the second pipette is configured to withdraw at least a portion of the re-dispensed fluid sample such that the second immobilized binding partner is brought into contact with the re-dispensed fluid sample to thereby form a second analyte-binding partner complex if a second analyte is present in the re-dispensed fluid sample.

9. A method for detecting the presence of at least two analytes in a patient'"'"'s single fluid sample, the method comprising the steps of:
-
upon receipt of a patient'"'"'s single fluid sample which may comprise at least two analytes, placing the patient'"'"'s single fluid sample in a sample receptacle; drawing the single fluid sample into a first pipette that is disposed within the sample receptacle, wherein a first immobilized binding partner is present on an inner surface of the first pipette and the first immobilized binding partner is brought into contact with the withdrawn single fluid sample such that a first analyte-binding partner complex is formed if a first analyte is present in the single fluid sample; re-dispensing a non-reacted portion of the withdrawn single fluid sample from the first pipette and into the fluid sample receptacle; drawing at least a portion of the re-dispensed fluid sample into a second pipette that is disposed within the sample receptacle, wherein a second immobilized binding partner is present on an inner surface of the second pipette, the second immobilized binding partner comprising an analyte specificity different from that of the first immobilized binding partner, further wherein the second immobilized binding partner is brought into contact with the re-dispensed fluid sample such that a second analyte-binding partner complex is formed if a second analyte is present in the re-dispensed fluid sample; and detecting the presence of the first analyte-binding partner complex and the presence of the second analyte-binding partner complex. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A kit for detecting the presence of at least two analytes in a patient'"'"'s single fluid sample, the kit comprising:
-
at least two pipettes, wherein the at least two pipettes comprises a first pipette having a first immobilized capture antibody specific to a first analyte present on an inner surface of the first pipette and a second pipette having a second immobilized capture antibody specific to a second analyte present on an inner surface of the second pipette, wherein the analyte specificity of the first immobilized capture antibody is different than the analyte specificity of the second immobilized capture antibody; a fluid sample receptacle, wherein the fluid sample receptacle is configured to hold a patient'"'"'s single fluid sample; and providing instructions to a user to allow the user to use the kit to identify the presence of at least two analytes in the single fluid sample.
