A method for detecting an antigen in a plasma or serum sample, which comprises conditioning the sample, wherein conditioning comprises either diluting the sample by a factor of at least 100 or dissociating the antigen in the sample from binding proteins with acid, base, or a chaotropic agent; drying the conditioned sampled; and detecting the antigen in the dried sample using an immunological assay is disclosed. The method is particularly useful for the detection of antigens associated with breast cancer. |
