Application-based market taxonomy splits demand across clinical diagnostics, veterinary health, food safety, and environmental monitoring, with clinical diagnostics contributing the dominant share. Within clinical diagnostics, infectious-disease antigen assays (SARS-CoV-2, influenza A/B, RSV and Group A Strep) represented 62 % of 2023 revenues, followed by pregnancy & fertility tests at 18 % and cardiac markers (troponin, CK-MB, BNP) at 7 %. Veterinary lateral flow, driven by pet-side parvovirus and feline immunodeficiency virus screening, is growing 9 % CAGR but remains under 10 % of market value because average selling prices are one-fifth of human assays. Food-pathogen detection kits (Salmonella, Listeria, aflatoxin) and environmental tests (mycotoxins, microcystin) together account for <7 %; these segments are limited by regulatory preference for quantitative methods and are price-elastic, yet they offer incremental pull-through for multiplex strips that broaden manufacturer margin.
