Immunoassay methods for measuring the concentration of an analyte in a test specimen are described. The methods use an immunoreagent, where one of the analyte and the immunoreagent is an antigen, and the other of the analyte and the immunoreagent is an antibody which specifically binds to the antigen. An important feature distinguishing these immunoassays over conventional immunoassays is that the standard sample containing a known concentration of analyte is measured in the same reaction vessel as the test specimen containing an unknown amount of analyte.
