The antigen is found on the patient sample. Since the test is a direct test, it detects antigen. The antigens detected are the elementary bodies.

The antigen is the entire foreign particle whereas the epitope is the specific binding site on the antigen that antibodies bind to. Antigens can have multiple epitopes with different structures.
