The types segment of the Bordetella Pertussis ELISA Kits market is organized around assay format and antibody class detection, primarily comprising IgG ELISA kits, IgM ELISA kits, multiplex ELISA kits, and competitive ELISA kits. IgG kits dominate because they measure long‑term immune response, essential for both clinical follow‑up and vaccine efficacy studies, thus driving the bulk of unit sales. IgM kits, targeting early‑phase infection markers, serve a niche but critical role in acute diagnostics, influencing pricing differentials. Multiplex kits enable simultaneous detection of multiple pertussis antigens or co‑circulating pathogens, attracting research institutions seeking higher data density, thereby expanding the market’s high‑value segment. Competitive ELISA kits, which quantify antigen concentration by inhibition, are favored in vaccine potency testing where specificity is paramount. Each type contributes distinct revenue streams, reflecting differing performance requirements, price points, and end‑user priorities, and together they shape the overall market taxonomy for Bordetella Pertussis ELISA Kits.
