Abstract
A novel method for detecting tumor associated antigen in patient's serum or plasma samples is provided. Tumor associated antigen in the form of immune complexes is detected by first applying the patient's serum sample to an immunoadsorbent column to enrich the amount of immune complexes relative to other serum components. The amount of tumor associated antigen is then detected in the enriched sample in a solid-phase assay employing a solid-phase receptor for the immune complexes and a labelling system specific for the tumor associated antigen.
