Molecular infectious disease testing refers to various approaches that are employed to identify and characterize infectious agents (viruses/bacteria, etc.) based on their genotype. Molecular infectious disease testing typically employs polymerase chain reaction (PCR), isothermal amplification methods and/or next generation sequencing (NGS) among others to provide the highest level of sensitivity and specificity. With the use of these molecular diagnostic techniques, clinicians can identify the pathogens causing illness and potentially develop a treatment plan that includes the appropriate use of antimicrobial agents. Molecular testing is also used to provide very early identification of infectious diseases; differentiation of one pathogen from another; and supportive decision-making.

Rising burden of infectious diseases to propel market demand

A major factor that is driving the growth of the molecular infectious disease testing market is the increase in the burden of infectious disease throughout the world as healthcare systems attempt to meet the increasing demands for the ability to detect, manage, and contain all types and forms of infections as rapidly and accurately as possible. Infectious diseases remain a leading cause of global mortality, with tuberculosis causing 10.7 million cases and 1.23 million deaths in 2024, while malaria recorded 282 million cases in 2024 (up 3% from 2023) and 610,000 deaths, compared to 598,000 deaths in 2023. Dengue incidence has surged with reported cases rising from 505,430 in 2000 to 14.6 million in 2024, highlighting the growing global infectious disease burden (Source: WHO). Urbanization, globalization, climate change, antimicrobial resistance, and ageing populations are collectively driving a rise in respiratory infections, sexually transmitted diseases, gastrointestinal diseases, tuberculosis, hepatitis, HIV, and vector-borne diseases worldwide. At the same time, the continuous emergence and re-emergence of pathogenic organisms is increasing the frequency and complexity of disease outbreaks. This has created a growing need for rapid-response and adaptable diagnostic solutions capable of addressing new and evolving disease threats as they arise.

The technology behind molecular testing directly addresses these current and anticipated clinical needs by enabling the early and precise detection and characterization of pathogenic organisms, even at the lowest levels of concentration, often at an earlier stage than the onset of severe clinical symptoms or when rapid or substantial transmission occurs. As the overall burden of disease increases, the reliance on clinicians and public health authorities for the distinction between viral or bacterial infections, the identification of co-infections, and for the selection of appropriate targeted therapy has increased, which has created a continual demand for molecular testing within hospitals, diagnostic laboratories, and public health agencies. There is an increasing burden placed on healthcare systems because of the increase in the number of patients infected by a variety of infectious diseases. In turn, the greater the number of infections, the greater the financial burden associated with the delayed or incorrect diagnosis of infectious diseases. To decrease the financial burden on healthcare systems due to delayed diagnosis of diseases or delaying treatment of patients, healthcare providers have started to utilize molecular diagnostic tests that assist in determining the appropriate course of treatment for patients more quickly, resulting in lower financial costs associated with treating patients and fewer hospital days spent by patients receiving treatment for their infections.

The rising rate of infections, coupled with the need for outbreak preparedness and controlling outbreaks, has placed an increasing emphasis on disease surveillance from the public health perspective. Molecular tests allow for the rapid identification of the causative agents of infectious diseases during an outbreak, support large-scale screening programs, and enable tracking of disease spread and mutation patterns. As a result, governments and other global health organizations are continuing to invest in the development of the capacity of molecular diagnostics as an integral component of the management of infectious disease outbreaks.

The increasing burden of infectious diseases has been and will continue to be a growing factor promoting long-term growth for the molecular-based testing market for infectious diseases. As the world moves to post-pandemic awareness, greater need for routine screening and higher expectations from healthcare professionals and patients regarding speed and accuracy of laboratory-grade testing will increase the market for molecular-based testing for infectious diseases.

Growth in point-of-care molecular solutions – A key growth opportunity

The rise of point-of-care molecular solutions provides a lucrative opportunity in the global molecular infectious disease testing market due to the impact these technologies have on where and how diagnostic tests are done. In contrast to traditional approaches to molecular diagnostic testing which is typically performed in centrally located laboratories with dedicated staff and complex equipment, a POC molecular test can provide laboratory level sensitivity and specificity at or close to the time of patient interaction, allowing for prompt clinical decision-making and increased access to quality testing. Emergency departments, outpatient clinics and primary care practices have experienced growing demand for prompt diagnostic testing, which supports the use of POC molecular platforms. The need for immediate treatment decisions when dealing with infectious diseases creates the risk of delays in diagnosis resulting in progressed disease state, greater disease transmission and increased healthcare costs. As an alternative solution to this issue, the availability of results from POC molecular testing within minutes to one hour enables healthcare providers to begin effective treatment during the same encounter. The value of this feature in dealing with respiratory infections, sexually transmitted infections, and hospital-acquired infections is substantial.

POC molecular testing also offers many options for decentralized and resource-limited environments, such as rural healthcare facilities, community-based clinics, or field-based public health programs, where centralized molecular laboratories are often absent. Compact and automated point-of-care systems with minimal preparation requirements support consistent and reliable testing capabilities in these settings, thereby increasing the potential for detecting and diagnosing disease in areas with high incidences of infectious disease. In addition, this will expand the scope of the molecular diagnostic market, to reach areas traditionally underserved by the laboratory network system. From a public health and health system viewpoint, the growth of POC molecular solutions advances and enhances outbreak management and infection control. Point-of-care testing performed in a rapid, onsite manner, facilitates early identification of cases, speedy decisions on isolation, and rapid initiation of treatment, thus slowing disease spread. Through increased awareness about POC molecular testing as a vital tool for epidemic preparedness, as well as facilitating routine surveillance, governments and health agencies are increasingly promoting the adoption of POC molecular diagnostics.

POC molecular platforms provide a unique, opportunity for manufacturers of consumables and cartridges, thereby simplifying the operation of end-users, and increasing the opportunities for manufacturers to generate recurring revenues. As technological advances lower the cost, increase the ease of use, and extend the multiplexing capability of POC molecular solutions, these technologies will emerge as an integral growth engine of the molecular infectious disease testing market; simultaneously, fulfilling unmet clinical needs and facilitating the broadest, fastest, and most equitable access to advanced diagnostic technologies.
