The type segmentation of the HLA Antigen Typing and Antibody Detection market distinguishes between two core assay categories: molecular typing and serological detection. Molecular typing, which includes PCR‑SSO, PCR‑SSP, and next‑generation sequencing (NGS) platforms, captures the majority of market growth due to its high resolution, scalability, and suitability for high‑throughput transplant programs. Serological detection, encompassing flow cytometry, ELISA, and Luminex‑based bead assays, continues to serve legacy laboratories and niche clinical settings where rapid antibody screening is essential. Within molecular typing, NGS is emerging as a high‑value sub‑type, offering comprehensive allele coverage and driving premium pricing. Conversely, within serological detection, Luminex technology has become the preferred sub‑type for its multiplexing capability, supporting both antigen typing and antibody screening in a single workflow. The relative contributions of these types shape overall market size, with molecular approaches projected to capture over 60 % of total revenues as healthcare systems prioritize precision medicine.
