Overview
New York, NY – July 21, 2025: The Global Infectious Disease Testing Market is projected to grow from USD 24.4 billion in 2024 to around USD 31.2 billion by 2034, expanding at a steady CAGR of 2.5%. This growth is driven by multiple factors, especially the increasing global burden of infectious diseases such as HIV, hepatitis, tuberculosis, and emerging threats like COVID-19 and monkeypox. According to the World Health Organization (WHO), globalization, urbanization, and climate change are accelerating the spread of these diseases, creating an urgent demand for faster and more efficient testing systems worldwide.
Government bodies and international health agencies are playing a major role in advancing diagnostic infrastructure. Many nations are investing in laboratory expansion, training programs, and rural testing access. The WHO has initiated several programs to assist countries in building robust disease surveillance and diagnostic networks. These developments are strengthening healthcare systems and ensuring that infectious diseases are diagnosed and controlled more effectively. Early detection remains central to stopping outbreaks, and this institutional support is increasing the global adoption of testing technologies.
The industry is also witnessing rapid innovation in diagnostic technology. Traditional testing methods are being replaced by advanced tools like PCR-based diagnostics, rapid antigen tests, and portable detection devices. These innovations provide faster, more accurate results and support quick medical decision-making. During outbreaks, these tools help contain disease by identifying cases early. Their growing use across both high-income and low-income countries reflects the global shift toward efficient and scalable testing options.
Another significant trend is the rise of point-of-care and home-based testing solutions. More individuals now prefer rapid tests that can be used at clinics or in their homes. These options are simple, do not need specialized lab equipment, and offer privacy. This shift in testing behavior has improved early diagnosis for diseases such as COVID-19, influenza, and sexually transmitted infections. It is also helping to reduce transmission in communities by promoting regular, convenient testing practices.
Developing countries are making strong progress in healthcare access, which is positively impacting the infectious disease testing market. Increased awareness about the importance of early diagnosis and rising healthcare spending are boosting demand. Global health organizations are partnering with these nations to enhance laboratory capabilities and deliver affordable testing solutions. Lastly, following the lessons of the COVID-19 pandemic, both global and national health authorities are investing in disease surveillance and emergency preparedness systems that depend heavily on regular and reliable diagnostic testing.
