Primary binding tests directly demonstrate and measure antigen–antibody binding reactions using chemical labeling with radioisotopes, fluorescent dyes, or enzymes. These tests are the most sensitive technique for measuring detectable antigen or antibody in a sample. Examples of primary binding serologic assays include radioimmunoassays (RIA), immunofluorescence (IF) assays, ELISAs, immunohistochemistry (IHC), Western blotting, and flow cytometry.
