Segmentation by Types classifies kits into three technological families: Immunoassay, Molecular, and Biosensor platforms. Immunoassay kits—primarily ELISA and lateral‑flow formats—dominate the market, contributing close to 55 % of sales, due to their established regulatory acceptance, ease of use, and cost‑effectiveness for high‑throughput screening. Molecular kits, centered on PCR and isothermal amplification, capture roughly 30 % of revenue; they are favored for detecting trace allergen DNA, offering superior specificity that commands premium pricing in manufacturing and laboratory settings. Biosensor kits—encompassing electrochemical, optical, and nanomaterial‑based sensors—represent the emerging 15 % share, driven by rapid readout times and potential for integration with digital traceability systems. Each type aligns with distinct user requirements and price structures, collectively forming a market taxonomy that informs investment priorities, R&D focus, and competitive positioning within the Food Allergen Detection Kit market.
