         8 . The device of  claim 7 , wherein the first immobilized capture antibody and the second immobilized capture antibody are selected from the group consisting of IgG, IgE, IgM, IgD, IgA, IgG1, IgG2, IgG3, IgG4, IgA1, IgA2, and combinations thereof. 
     
     
         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on an inner surface of the first pipette and the first immobilized binding partner is brought into contact with the withdrawn single fluid sample such that a first analyte-binding partner complex is formed if a first analyte is present in the single fluid sample;   re-dispensing a non-reacted portion of the withdrawn single fluid sample from the first pipette and into the fluid sample receptacle;   drawing at least a portion of the re-dispensed fluid sample into a second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.   
     
     
         10 .
