1. A process for producing a tray for carrying out immunogenic reactions to determine the presence of a component of an antibody antigen reaction in a biological fluid sample through the use of reagents comprising:

  • (a) providing a plastic plate member formed from a hydrophobic plastic with a top and bottom surfaces, the top surface of said plate member defining a plurality of spaced apart wells in said top surface, with said wells having a bottom and side wall the inner surfaces of which being configured and adapted to hold and receive a biological fluid and reagents for conducting an immunogenic reactor; and

    (b) selectively treating the inner surface of said bottom wall of the wells to render said inner surface of said bottom wall hydrophilic without affecting the hydrophobic nature of the inner surface of the side wall.
