Report Overview

Global Immunodiagnostics Market size is expected to be worth around US$ 44.9 Billion by 2034 from US$ 21.6 Billion in 2024, growing at a CAGR of 7.6% during the forecast period from 2025 to 2034. In 2024, North America led the market, achieving over 45.6% share with a revenue of US$ 9.8 Billion.

The immunodiagnostics market is witnessing robust growth, primarily driven by continuous innovation in biotechnology and the development of advanced diagnostic techniques. Prominent technologies such as Enzyme-Linked Immunosorbent Assay (ELISA), Chemiluminescent Immunoassays (CLIA), and Fluorescent Immunoassays (FIA) are transforming diagnostic methodologies by accurately identifying antigen-antibody interactions, which are essential for detecting a wide range of diseases.

These diagnostic processes depend on various critical components, including fluorescent chemicals, enzymes, substrates, and buffer solutions. Their widespread application in hospitals, clinical laboratories, and research institutions underscores their importance in modern healthcare diagnostics.

The National Institute of Biologicals (NIB) plays a pivotal role in ensuring the quality and reliability of immunodiagnostic test kits. It conducts quality control testing for kits used in crucial applications such as blood donor screening. Regulatory oversight is provided by organizations including the Central Drugs Standard Control Organization (CDSCO) and the National AIDS Control Organization, which help maintain high standards of safety and efficacy.

Thermo Fisher Scientific Inc. is a key player in the in-vitro diagnostics landscape. The company offers a broad portfolio of diagnostic tests for conditions like allergies, asthma, and autoimmune diseases. With annual revenues surpassing USD 40 billion and a global network involving over 125,000 collaborations, Thermo Fisher significantly contributes to the expansion and innovation of the immunodiagnostics market.

The rising prevalence of chronic and infectious diseases is a major driver of market growth. According to the Centers for Disease Control and Prevention (CDC) in 2023, there were approximately 1.2 million people living with HIV in the United States in 2021, with a significant portion unaware of their infection. This emphasizes the urgent need for early diagnostic solutions. Similarly, the American Cancer Society (ACS) projected around 238,340 new cases of lung cancer in the U.S. in 2023, highlighting the increasing burden of cancer and the necessity for timely diagnosis.

Globally, the World Health Organization (WHO) reported that 18 million people were living with rheumatoid arthritis (RA), with women representing a substantial majority of those affected. The aging population and rising incidence of chronic diseases are driving the demand for more efficient and accessible diagnostic tools.

Another key factor contributing to the market’s growth is the increasing demand for point-of-care (POC) testing. Healthcare systems globally are shifting towards faster and more efficient diagnostic solutions that offer rapid results at the patient’s bedside, in remote areas, or outpatient settings. POC testing reduces dependence on centralized laboratories, enabling quicker clinical decision-making. This is particularly important for infectious diseases like COVID-19, influenza, and tuberculosis, as well as chronic conditions such as diabetes and cardiovascular diseases.

The integration of immunodiagnostic tests into point-of-care platforms is driving technological innovation in the sector. Advanced technologies such as microfluidic devices, biosensors, and AI-based diagnostics are revolutionizing immunodiagnostics, allowing for more accurate and timely results. These innovations are expected to continue expanding the market, enhancing the accessibility and reliability of diagnostic solutions globally.

Driving Factors

Rising Prevalence of Infectious and Chronic Diseases
The increasing global burden of infectious and chronic diseases is a primary driver of the immunodiagnostics market. Conditions such as HIV, hepatitis, cancer, diabetes, and cardiovascular diseases require early and accurate diagnostic testing for effective treatment. According to the World Health Organization (WHO), noncommunicable diseases account for 74% of global deaths, highlighting the critical need for diagnostic solutions.

Immunodiagnostic tests, such as ELISA and CLIA, play a key role in detecting biomarkers associated with these diseases. The demand for accurate, rapid, and minimally invasive diagnostics has intensified, especially in low- and middle-income countries. This growing healthcare burden continues to boost investment in immunodiagnostics technologies across hospitals, laboratories, and point-of-care settings worldwide.

Trending Factors

Shift Toward Automated and Point-of-Care Testing
A major trend in the immunodiagnostics market is the transition toward automation and point-of-care (POC) testing. Automated platforms improve test throughput, reduce human error, and allow for high-volume testing—critical in hospital and clinical lab settings. Meanwhile, POC immunodiagnostics enable rapid diagnostics at the patient’s bedside or in remote locations, significantly improving clinical outcomes and reducing treatment delays.

Technological innovations, such as portable immunoassay analyzers and integration with digital health systems, support real-time decision-making and remote patient monitoring. These trends are further accelerated by the global push for decentralized healthcare models and the growing adoption of telemedicine. As a result, manufacturers are focusing on compact, user-friendly, and AI-integrated testing devices.

Restraining Factors

High Cost of Advanced Diagnostic Systems
One of the significant restraints in the immunodiagnostics market is the high cost of advanced testing equipment and reagents. Immunoassay platforms such as chemiluminescent immunoassay (CLIA) systems require substantial capital investment, which limits their adoption in low-resource settings. Additionally, the cost of high-quality reagents, maintenance, and skilled personnel adds to the operational expenses.

Smaller clinics and diagnostic centers in developing regions may find these expenses unsustainable, leading to underutilization of modern diagnostic technologies. Reimbursement challenges and inconsistent insurance coverage further compound this issue, particularly in markets with fragmented healthcare systems. Consequently, affordability remains a key barrier to the widespread adoption of next-generation immunodiagnostic solutions across all geographies.

Opportunity

Expansion in Emerging Markets and Home Testing
Emerging economies present significant growth opportunities for the immunodiagnostics market due to rising healthcare investments and growing awareness of disease prevention. Countries in Asia-Pacific, Latin America, and the Middle East are expanding diagnostic infrastructure to meet increasing demand for early disease detection. The growing penetration of health insurance and government-backed screening programs enhances market accessibility.

Additionally, the trend toward home-based diagnostics and self-testing is opening new market segments. Immunodiagnostic kits for conditions such as pregnancy, COVID-19, and infectious diseases are now available over-the-counter, supporting decentralized healthcare delivery. With further technological advancements and cost reductions, the home testing market is expected to grow rapidly, especially in post-pandemic healthcare models.

Regional Analysis

In 2024, North America held a dominant market position, capturing more than a 45.6% share and holds US$ 9.8 billion market value for the year. This leadership is driven by several key factors. The region has a well-developed healthcare infrastructure and high diagnostic testing rates. A strong presence of advanced hospitals and laboratories supports the use of automated immunoassay platforms.
