ABSTRACT:
Methods and compositions are provided for performing an assay on whole blood samples. The method is for a determination of an analyte which is a member of a specific binding pair (sbp) consisting of ligand and homologous receptor. The method involves a binding agent for the red blood cells in such sample, a solid bibulous element to which is bound at least one sbp member, and a signal-producing system. The method comprises combining the whole blood sample, the binding agent, and none or, where appropriate, one or more members of the signal producing system. The medium is next contacted with a portion of a solid bibulous element to which is bound one of the members of the specific binding pair to allow the medium to traverse such element (immunochromatography). The solid bibulous element is contacted with any remaining members of the signal producing system. Signal resulting from the signal producing system is detected and is related to the amount of the analyte in the sample.
