Abstract
A sample device and method for assaying samples containing members of immunological pairs by chemiluminescence include a first chamber wherein antibody-conjugated reagent antigen labelled with a chemiluminescence moiety is displaced from the antibody by sample antigen. The labelled reagent antigen diffuses into a second chamber, wherein the chemiluminescence moiety reacts with cofactors to produce a light emission proportional to the amount of sample antigen present.
