The FSH Test Kit ecosystem encompasses a complex network of participants, from upstream technology providers and suppliers to downstream end users. This ecosystem can be broadly segmented into three main stages: upstream, midstream, and downstream. Upstream participants, such as raw material suppliers and technology providers, create the foundational components and technologies used in FSH Test Kits. Midstream participants, including OEMs and system integrators, assemble and integrate these components into finished products. Downstream participants, comprising distributors, service providers, and end users, facilitate the distribution, maintenance, and consumption of FSH Test Kits, ultimately capturing value.
