The global swab home test market has experienced explosive growth in recent years, driven by the increasing demand for convenient, rapid and private diagnostic solutions. As of 2025, the market size is expected to exceed USD 28 billion, with China emerging as a core production and innovation hub. Benefiting from a complete industrial chain covering raw material supply, precision manufacturing, and strict quality control, Chinese manufacturers have won global recognition for their reliable product quality, cost-effectiveness, and rapid response capabilities. These enterprises not only meet domestic public health needs but also export their products to over 150 countries and regions, supporting global disease prevention and health management.
