1. In a method of performing an immunoassay of a fluid specimen to determine immune complexes therein, the steps comprising:

  • treating a solid phase, plastic base having means for receiving the fluid specimen to be assayed, to produce a layer of a non-proteinaceous non-ionic polymer on said means, said polymer adhering to said plastic base and having the capability of absorbing immune complexes which may be present in such specimen;

    placing the fluid specimen to be assayed on said receiving means;

    permitting said polymer layer to absorb immune complexes present in said specimen; and

    treating said layer in a manner to produce an indication of the amount of immune complexes in said layer.
