The Assays & Reagents segment is projected to account for 47.5% of the infectious disease diagnostics market revenue in 2025, emerging as the leading product category. This growth has been fueled by the high-frequency usage of consumables in diagnostic workflows, especially in centralized laboratories and point-of-care settings.
Clinical demand for rapid, sensitive, and scalable testing solutions has increased reliance on specialized reagents and assay kits that deliver accurate results across a range of pathogens. Product development efforts by diagnostics companies have prioritized ready-to-use, multiplex-capable assay kits, which enhance lab productivity and reduce turnaround times.
Furthermore, global health initiatives aimed at expanding testing access in underserved regions have focused on affordable and easy-to-deploy reagent systems. With infectious disease testing often requiring repeat screening and follow-up diagnostics, the consistent consumption of assays and reagents has supported recurring revenue generation. These factors are expected to secure the continued dominance of this segment in the diagnostic supply chain.
The Human Immunodeficiency Virus (HIV) segment is projected to contribute 34.8% of the market revenue in 2025, holding the leading position in the disease type category. This segment’s growth has been driven by the ongoing global burden of HIV, with millions requiring routine viral load monitoring, early detection, and antiretroviral therapy (ART) initiation.
Public health policies and global funding mechanisms have prioritized universal access to HIV testing, particularly in high-prevalence regions, creating strong demand for reliable diagnostic platforms. International healthcare agencies have reported a surge in the use of combination rapid tests and nucleic acid testing (NAT) for both screening and confirmatory purposes.
Continuous innovation in HIV diagnostics, including the development of self-test kits and digital result interpretation tools, has expanded patient outreach and decentralized testing capabilities. As global efforts persist toward ending the HIV epidemic through early diagnosis and treatment linkage, the HIV segment is expected to maintain its strategic significance within infectious disease diagnostics.
The Immunodiagnostics segment is projected to represent 41.6% of the infectious disease diagnostics market revenue in 2025, retaining its lead in technology adoption. Growth in this segment has been propelled by the widespread use of enzyme-linked immunosorbent assays (ELISA), lateral flow assays, and chemiluminescence-based platforms in the detection of bacterial, viral, and parasitic infections.
Healthcare providers have favored immunodiagnostics for their high specificity, rapid results, and cost-effectiveness, especially in large-scale disease surveillance and screening programs. Diagnostic manufacturers have expanded their immunoassay portfolios with automated platforms that reduce technician dependency and improve throughput in clinical laboratories.
Moreover, immunodiagnostics have been integral in pandemic response strategies, where scalable and accurate serological testing was essential. Technological advances enabling multiplex immunoassays have further enhanced utility across co-infection scenarios and endemic diseases. As global health programs continue emphasizing preventive screening and early detection, immunodiagnostics are expected to remain the foundation of infectious disease testing technologies.
The increasing incidence of infectious diseases such as COVID-19, HIV, tuberculosis, malaria, and influenza has heightened the demand for effective diagnostic tools. This surge is largely due to the global rise in population, increased travel, and urbanization, which facilitate the spread of infections.
Innovations in diagnostic technologies, including molecular diagnostics, polymerase chain reaction (PCR), next-generation sequencing (NGS), and point-of-care (POC) testing, have revolutionized the market. These technologies offer rapid, accurate, and early detection of pathogens, which is crucial for effective disease management and control.
Governments worldwide are investing heavily in healthcare infrastructure and disease surveillance programs. Funding for research and development in infectious disease diagnostics is increasing, driven by the need to prepare for and respond to pandemics and other infectious disease outbreaks.
Public awareness regarding the importance of early detection and diagnosis of infectious diseases is growing. This awareness is supported by healthcare campaigns and educational programs, which emphasize the benefits of early intervention in managing and controlling disease spread.
Rising healthcare expenditure globally is enabling better access to advanced diagnostic tools and services. This is particularly evident in developing countries where improving healthcare infrastructure is a priority, thereby boosting the adoption of infectious disease diagnostics.
Globalization has led to increased travel and trade, contributing to the spread of infectious diseases across borders. This has created a heightened need for robust diagnostic systems to monitor and control outbreaks, especially at ports of entry and among travelers.
The global aging population is more susceptible to infections due to weakened immune systems. As a result, there is a higher demand for diagnostic testing among the elderly, driving market growth.
The emergence of new and re-emerging pathogens, such as the Ebola virus, Zika virus, and most recently, SARS-CoV-2, necessitates the development and deployment of new diagnostic tests. The dynamic nature of pathogens requires continuous innovation in diagnostic approaches.
The increasing preference for point-of-care testing, which provides rapid results and can be conducted outside traditional laboratory settings, is a significant driver. This trend is particularly important in remote and underserved areas where access to centralized laboratories is limited.
The private sector is playing a crucial role in the development of new diagnostic technologies. Pharmaceutical and biotechnology companies are investing in research and development to create more effective and user-friendly diagnostic tools, driven by the lucrative potential of the market.
